The University Of Louisville Libraries - A Library of the 21st Century

Whilst in Louisvlle attending a seminar on contemporary American literature and touring various sites of cultural interest the University Library was one of those sites that had a never-fading impression on my mind not only for its unique architectural plan but for other inexpressible qualities that make it an ideal place for quiet and serene study. My first visit was when the Director of our program led us there for an induction into the use of computers and the internet in literature research. The room we were led into for the class was fully equipped with computers in all the over fifty desks for students and a master screen monitor for the instructor. Many other rooms including the state of art auditorium were equally well equipped.

I passed through the library on many other occasions. But the most significant one was when on my way from the University post office the thought occurred to me of recording the beautiful vistas of the campus in pictures as well as in mind and one such was the Ekstrom Library which represented to me the focal point of all the other libraries scattered at various ends of the expansive campus.

I took about two views of this building and I was still gaping in wonder especially at the bewitching splendor of its frontage with readers combining eating and relaxing. I was particularly struck by its inviting, comfortable, and open space teeming with students and bustling with activity, a lovely terrace equipped with outdoor furniture, facing a pleasantly inviting green outdoor space, exploiting the favorably warm climactic conditions here for enjoying nature. Taking advantage of the generally mild Kentucky weather with its ample, inviting green space, students can study or just catch a break at a number of outdoor tables on the terrace. On nice days, there are few better places to study-and certainly it makes for an inviting entry

I found myself wandering in to get a better view. As I wandered through I remembered my mission of seeking support for our resources-starved university libraries in Sierra Leone. My search for the head led me into the office of Mr David Hogarth who instantly became an able facilitator of my mission enabling me within a week to meet the Dean of libraries.

Whilst awaiting my appointment with her I was led on a tour of various parts of the Ekstrom library. This library, I learnt, holds more than 1.1 million and 5,100 journal subscriptions supporting research and curricula in the humanities, social sciences, business and education. It also contains large collections of microforms, government publications, multi-media and current periodicals, the Granville A. Bunton Pan African Collection, the Barbara S.Miller Multiracial Children's literature Collection and the Bingham Poetry Collection.

The Rare Books and Photographic Archives provide rare research sources for scholars and other researchers. African American collections, English, European, and American Literatures collections together with the substantial space given to reference and reserved books make this library a very significant research as well as information disseminating tool. But it is also a repository and exhibitor of many prized manuscripts and other documents like for example the outstanding 1482 first printing of Euclid's Elementia and a copy of the Principia with annotations in Newton's hand. The working collection of Richard M. Kain, and the first editions and manuscripts of James Joyce and W.B. Yeats preserve much of Irish Literary Renaissance heritage. There is also quite a good collection of Modern English and American writers with noteworthy editions by 1890's authors and books as well as autographed letters from members of the Bloomsbury Group.

A famous and ever-growing and rich collection of special materials, archives and photography include:

Roy and Dela White Collection of Edgar Rice Burroughs.

Arthur J. Slavin.Collection of English History.

Hattie Winston Collection of African- American Scripts and Screen Plays.

Irwin Hilliard Archive of Fine Bindings.

Billy Davis 111 Collection of Aerial Photography.

Other special collections include the James Chandler World War Posters and Lafin Allen's Kentucky Maps.

The photographic Archives houses more than 2 million photographs and manuscripts as well as fine art prints. It also offers printing services and a rotating series of exhibits.

The Roy Stryker Papers include photographs and manuscripts from documentary projects directed by Stryker at the Farm Security Administration, Standard Oil Company and Jones and Laughlin Steel. The Cautfield and Shook Royal Photo and Lin Caufield collections consist of photographs from Louisville's past. Whilst the Lean Thomas, Matlack Studio, Arthur Y Ford and Henderson Settlement School collections document life and culture in Appalachia. 2,000 prints by many notable American artists such as Paul Caponegro and Gary Winogrand constitute the library's Fine Print Collection.

The library also serves a much wider community beyond the campus.Through e-mail, phone or in person one could request and receive help or even fix a session with a research librarian here. A Cardinal card enables you to check out up to 99 items at a time and renew books on-line. Visiting academics are entitled to inter-library loans of up to 15 books. A University of Louisville student enjoys the privilege of searching for items reserved for his class on-line. Minerva gives on-line access to catalogues and gateways to many collections. University of Louisville distance learners could access off-campus through their ULINK username and password both library assignments by their professors and electronic databases of library resources for self-directed research from non-University of Louisville internet addresses.

Ekstrom Library houses and lends resources to the Delphi and the Writing Centers. The Delphi Center helps professors use technology in their teaching and prepares them to teach courses online. The writing center assists students, professors and staffs with writing projects and holds workshops on improving writing skills. Through this center an appointment with a writing consultant could be scheduled and important writing resources found.

The University of Louisville libraries a conglomerate of libraries stocking books on few selected disciplines such as music, visual art, health sciences, engineering, physical science and technology at the time of my tour was in the process of moving in to Ekstrom the main library, the over 149,000 volumes constituting the engineering, physical science and technology books and journals.
Besides the William Ekstrom main Library, the University library network consists of: The Kornhauser Health Sciences Library; The Dwight Anderson Music Library; The Margaret M. Bindwell Art Library; and The University Archives and Records Center.

The Kornhauser Health Sciences Library a comprehensive and the most current health sciences information resource center is also a "Regional Resource Library" in the National Network of Libraries of Medicine. It represents a significant resource for the entire health sciences community of the Louisville metropolitan area and the western half of Kentucky. It has over 250,000 volumes, 2,700 journal subscriptions, audiovisual materials and a variety of electronic formats. It stocks numerous items relating to health care in Kentucky and the Trans-Appalachian West, including historical collections, the medical school archives, book manuscripts and physical objects.

The Dwight Anderson Music Library providing user-centered services offers seamless access to information resources in all formats and serves as a center for teaching and learning which supports the University of Louisville School of Music curriculum and research. It houses the largest academic music collection in Kentucky including the Gravemeyer Collection of Contemporary Music comprising all submissions to the internationally renowned Music Composition Award as well as a large assortment of sheet music containing thousands of Louisville imprints celebrating the history of music publishing in the city and the "Traipin Woman" collection with its emphasis on American folk song.

The Margaret M. Bridwell Art Library with its more than 80,000 volumes is a gateway to information for teaching, research and scholarship in art, design, art history and architectural history. It subscribes to over 300 domestic and foreign journals and museum bulletins. It has also hundreds of videos and provides access to the major electronic and print indexes. Subjects covered here include painting, drawing, sculpture, print-making, photography, architectural history 45, interior design, graphic design, art education, pottery, fiber arts and decorative arts. It also holds approximately 3,000 rare and scarce volumes and about 150 linear feet of archival materials.

The librarians strive concertedly with academic staff to meet the information literacy and research needs of a diverse population recognizing that libraries are an essential tool in the University's mission to become a premier nationally recognized metropolitan university.

The University of Louisville libraries is guided in all its undertakings by its vision that libraries are the academic heart of the university and a place for discovery and learning outside the classroom and the lab. They therefore seek to participate as active and integral partners in meaningful learning, outstanding teaching and effective research. Users are therefore always being instructed on information availability and use. Services and resources are tailored to suit the varying needs of users. Library staff thus identify, evaluate and select materials of varying formats to develop collections that meet user needs. They also apply technology, research and instructional innovations to enhance services and access to traditional and electronic collections.

Rapid expansion in stocks, rapid technological advancement including the introduction of a robotic retrieval system has enabled more books than could be retained in the library halls being stacked in trays which are accessed by computers on user request. The system gives the library enough space for over three million volumes. The less frequently used volumes will be loaded into the system, and students can still browse titles in open stacks in the old wing of the library. Books stored in the RRS are identified as such in MINERVA, the library's catalog. To request the item, patrons click on a live "request" button onscreen, and then a robotic crane is sent off to find the item, moving among racks of steel bins holding books and journals from which the robotic arm selects, grabs and delivers the appropriate bin to a pickup station where a library attendant pulls the exact item and delivers it to the circulation desk within minutes. The entire process which I witnessed myself takes only minutes and handles numerous simultaneous requests.

Having the RRS, I was told, also saves the library the cost of a courier service and the additional library staff needed to operate a remote storage facility. The Ekstrom Library's RRS stands out in how artfully it is built into the central design of the new addition. With numerous windows on the system, students can literally stand at the circulation desk, make a request, and actually see the system fill their form watching it work serving almost as a piece of 21st-century art, a book fountain of sorts, whizzing and whirring volumes past the windows. In all, the Ekstrom addition contributes a hefty 42,500 square feet of space to the library

The library's robotic retrieval system (RRS) has freed up significant space for exhibits in the library, like the one by Split Rock Studios, St. Paul; designer, Lisa Friedlander that highlights the year of Kentucky's founding and features a statue of Henry Clay, Kentucky senator from 1806 to 1850. The desk is a replica of the desk Clay used when he was in the Senate-the actual desk is in the office of Kentucky Senator Mitch McConnell, who endowed the Ekstrom expansion and the McConnell Center for Political Leadership.

The libraries now seem poised to attain the ambitious goals of the university of becoming a premier metropolitan university that is nationally recognized for advancing intellectual, social and economic development. The library's massive atrium allows light to pour into the building and over the circulation desk.

The libraries' technological resources have developed to state-of-the-art electronic information centers for the campus community with more than 550 computer workstations from which one can borrow laptop computers for use anywhere in the libraries. Advanced wireless technology enables laptop users to access the internet and the libraries' vast electronic resources. Researchers could access 25,000 full-text journals and hundreds of electronic databases.

Two teaching laboratories enable librarians to conduct classes in the library with instant access to the online world. The library's three new, modern instruction labs equipped with wireless technology and state-of-the-art audiovisual equipment, emphasize the library's continually expanding role in teaching and learning. Instructional Lab 1 and Instructional Lab 2 have become extremely flexible spaces hosting a version of the 3M Road Show for Kentucky librarians.

The university community can access thousands of electronic information resources from hundreds of computer work stations in the libraries and also from anywhere: their offices, classrooms or home. Minerva, the online catalogue indexes and accesses the many items held within the libraries. Through its access to national and regional electronic networks one could search many library catalogs and databases around the nation and even around the world.

The University of Louisville Libraries is a member of the Association of Research Libraries, the most prestigious and influential library association in North America. Strong financial support from the University administration has propelled it up to national prominence and impetus in strengthening its ties with Metroversity, a consortium of higher education institutions in metro Louisville, Kentucky, Virtual Library and other library consortia in the region and nation thus adding significantly to the materials made available to its students and faculty and to students and faculties from other campuses.

It has established Kentucky's first library chair, the Evelyn J. Schneider Endowed Chair For Scholarly Communication underwritten by the estate of a longtime university librarian and the state's Research Challenge Trust Fund. The first chair holder, Dwayne K. Butler is a highly regarded expert in copyright law, particularly that related to educational and electronic resources.

Overseeing all these developments for the past eleven years has been a charismatic, energetic, ingenious and visionary woman, Prof Hannnelorewery Rader, Dean of Libraries, whom I had the privilege of talking to. Prof Radar brought to Louisville a wealth of experience. For seventeen years she headed the Cleveland and Wisconsin university libraries and held various positions at Eastern Michigan University for almost twelve years. She has written widely in her field and attended many professional conferences. She was eventually named in 1999 Outstanding Academic Research Librarian.

Through Dr Radar's innovative ideas, her drive and direction together with the expanding library collection, upgraded resources, a more inviting environment, helpful and innovative library staff and academics library usage has recorded a 60 percent increase thus exceeding the 2 million per annum mark. One of her striking innovations is the Tulip Coffee Shop in the spacious lobby where readers enjoy tasty sandwiches and other relishing rolls with cups of tea, coffee orange juice or diet coke as they read or scroll through the internet. The Tulip Tree Café has become so popular that it may soon need to add another cash register.

Louisville offers one of the nation's best information literacy programs. Louisville libraries are no longer just places for research, but are now like other libraries today places of active instruction.
According to Prof Radar, her philosophy is to cater for the needs of the mostly non-traditional studentship mostly adults of varying ages and non-residential for increasingly comfortable atmosphere and facilitating the processes of accessing information. This explains her introduction of the snack bar and the constant restructuring and redecorating of the premises.

"We wanted to have a space where students could learn and do research but also socialize. ... We wanted to offer a library space for all of those things," for as she stressed "Our students are urban, many are part-time and don't live on campus. We want them to be on campus." To accomplish that, she says, they completely reimagined their library for the 21st century.

"Space was an issue," Rader says. "We were running out of space for our materials, and that's pretty much a problem for most academic libraries." Today, the library space is more than repository but a place for instruction, to showcase unique holdings and exhibits, and to foster student collaboration and all forms of interaction, both with information sources in all formats as well as with librarians.

With space a key concern, the highlight of the Ekstrom Library expansion is its robotic retrieval system, a unique system made up of more than 7000 steel bins, offering climate-controlled storage for up to 1.2 million volumes. Rader was already familiar with how efficient the system could be, having come from Eastern Michigan University, Ypsilanti, one of the first to install such a system. "We never really considered an off-site storage facility," as she said. "We don't want to store the books miles away, send for them when a student needs them, and then wait to have them delivered to campus." For as she notes, the robotic system can retrieve and deliver a book in a matter of minutes while off-site storage can sometimes take days.

The University of Louisville being a public institution, open to the general public,it is, according to Rader putting an even greater premium on space and efficiency. So rather than filling the space with immovable objects, such as banks of PCs, it is completely wireless and filled with flexible seating, from stuffed, comfortable chairs and small tables to wooden chairs and large, roomier tables for students to spread out their work. "Students can bring their own or check out laptops at the circulation desk." Meanwhile, 600 traditional workstations remain in the old wing for those who wish to use them.

The Libraries in their entirety, the Dean told me, hold millions of print volumes from many countries, electronic books and databases and thousands of electronic journals, reference materials, other library resources, library guides and services.

In addition to increased room for student collaboration, the library expansion features three new library instruction labs, where formal or informal classes are held, and the charming new 150-seat Elaine Chao auditorium, all handicapped accessible, and equipped with the latest technology, including wireless Internet access and state-of-the-art AV equipment.

With digital resources offering access to information, much of the library's space is freed up for the library's more unique holdings. An ambitious slate of lectures, seminars, conferences, exhibits, and displays, all designed to engage students, faculty, and the community in the library have been laid out as ongoing activities. Chao, who serves as Labor Secretary under President Bush, spoke recently in the auditorium that bears her name.

In addition, the library is home to the McConnell Center for Political Leadership, featuring the papers and exhibits of Kentucky's Republican Senator Mitch McConnell. The bipartisan center sponsors a range of programming, including lectures and seminars. In fact, the Ekstrom expansion owes a great deal to the McConnell Center-the .2 million project was funded by federal grants earmarked by McConnell.

The Elaine L. Chao auditorium is named for the current U.S. Secretary of Labor and plays host to a full slate of lectures and seminars. The space between the rows is exceptionally wide, preventing cramped knees or contortions to allow people to pass. The acoustics in the auditorium are "perfect," making the space the university president's favorite venue for press conferences presenting a great location for TV cameras, press feeds, etc. Chao herself recently spoke there, as has Sen. Edward Kennedy (D-MA).

To Radar though it's still a library storing information, it is also a place for people to hang out, a place for the whole university, a space to be, a space for events, for special teaching and learning sessions." a 21st-century library."

Network Cabling and Installation

Have you ever wondered what it is that connects computers and networks to one another? Network cable in conjunction with the associated hardware (network switches, hubs, demarcation equipment) is responsible for computers being able to connect and transfer data across intranets (internal network) and the internet. Network cabling today is used for many other purposes besides computer networking. It can be used to carry video for security camera systems as well as video for cable TV and AV (Audio/Visual) applications. Network cabling is also used as control cable in Building Maintenance Systems and Access Control Systems. There are several different types of cables that are used for this purpose, including unshielded twisted pair, shielded twisted pair, fiber optic and coaxial. In some cases, only one type of cable is used in a network, while in other cases, many different types are used. Wireless systems are becoming more and more popular but always remember you still need network cabling for the wireless system. There is still two things that make network cabling better than a wireless network: it is much more secure and reliable.

Understanding Cable Type

Before you can really understand how cable networking works, you need to know about the various cables and how they work. Each cable is different, and the type of cable used for a particular network needs to be related to the size, topology and protocol of the network. Here is a rundown of the cables that are most commonly used for network cabling:

Unshielded/Shielded Twisted Pair - This is the type of cable that is used for many Ethernet networks. There are four sets of pairs of wires inside the cable. There is a thick plastic separator that keeps each pair isolated through the run of cable. Each pair of wires are twisted so there will be no interference from other devices that are on the same network. The pairs are also twisted at different intervals so they will not cause interference between themselves. In an application where there is a lot of Electromagnetic Interference (EMI), such as a mechanical space, you may choose to use shielded twisted pair, which has an outer shielding that adds extra protection from EMI. Category 5e, 6, 6A and 7 are the general choices today. Twisted pair cable is limited to 295' on a horizontal run. Twisted pair cable is used for many applications. Standard station cabling for computers and VOIP phones, wireless access points, network cameras, access control and building maintenance systems are just a few. This is one of the most reliable types of cables, and when used, network failures are less common than when other cables are used.

Fiber Optic - Fiber optic cable is primarily used as backbone cable although it is being used more and more as station cable (think FIOS). By backbone cable I mean it connects Telecommunication Rooms within a space to each other. Fiber optic cable has huge broadband capacities which allow it to carry large amounts of information as super fast speeds. Fiber cables can cover great distances(hundreds of meters) as opposed to copper cable. Because these cables must work so hard and the information travels such distances, there are many layers of protective coating on fiber optic cables. Fiber cables transmit light as opposed to electrical current. Fiber optic cable requires much less power than high speed copper does. Fiber optic cable is a great choice for high speed reliable communications.

Coaxial Cable - Coaxial cable usually falls under the scope of work of the network cabling installation contractor. Coax will be used for the cable television locations within the space you are cabling. The service provider will drop off the outdoor cable at the point of entry. The contractor will run an extension (usually RG-11) to the local telecom closet within the space. The individual station runs(RG-6) will terminate on a splitter to connect to the service cable. The center of this type of cable has a copper conductor and a plastic coating that acts as an insulator between the conductor and the metal shield. This cable is covered with coating, which can vary in thickness. The thicker the coating, the less flexible it is going to be. There are a few types of terminations for coax. Compression, crimp and twist on are the three types of terminations. The best method is compression as long as they are performed correctly. Crimp terminations are also reliable and require the right tool for the particular connector you are using. I would not recommend twist on as they are not reliable and prone to problems. A few types of coax connectors are F connectors, BNC connectors and RCA connector.

Network Cabling Components

Patch panel - This is the panel where all of the station cables terminate within the Telecommunications Room. They are usually mounted on a wall mount or floor mount telecommunications rack. Typically there are 24, 48 or 72 ports on a patch panel. There are a few different styles such as angled or straight. Panels also have the option of having the 110 type pins attached to the back of the panel or you can terminate jacks and snap them into the empty panel.

Data Jack - This is the connector where each individual cable is terminated out at the station side. The jacks are snapped into a faceplate ranging from 1 to 8 ports typically. Data jacks can be terminated in a 568A or 568B pinout. Check with the customer or designer for the correct pinout.

RJ 45 Connector - The RJ-45 connector is installed on the end of a network cable. They are 8 pin connectors. The most common place to find the RJ 45 is on a cable terminating at a wireless access point. The RJ 45 is a male connector and would plug into the port on the WAP.

Wireless Access Points - These are devices that transmit network access wirelessly. Typically they are mounted on the ceiling or wall. A wireless survey would need to be performed to maximize the correct placement of WAP's. Contrary to popular belief wireless devices STILL need to be fed with network cabling.

Cable Supports - (Commonly called J-Hooks) Cable supports are mounted in the ceiling as a support structure for your cable bundles. Main path cable supports should be mounted to the concrete deck ceiling within the space. You are no longer permitted to hang j-hooks from ceiling supports, electrical or plumbing pipe or any other system infrastructure.

Wire Managers - Wire managers are installed between patch panels and switches to manage patch cables. They serve a very important purpose as they keep law and order in a Telecommunications Room. Nothing irks me more than finishing a brand new beautiful install and having the IT group come in and not use the wire managers. It ruins the aesthetics of the job. In addition it sets a bad precedence from the birth of the Telecommunications Room that others are sure to follow.

Firestop Sleeves - Firestop sleeves are a vital part of any network cabling installation these days. Gone are the days of just banging holes into sheetrock and passing cables through. When you penetrate any firewall on a job you must install a firestop sleeve. There are specific products made for this. EZ Path and Hilti both make excellent versions in varying sizes. You can install a sleeve of EMT pipe through a wall also as long as you use firestop putty or firestop silicone to seal off all openings. This can save lives and minimize damage in the event of a fire.

Cable Labels - All cables and termination points should have a unique label. This makes installation, maintenance and troubleshooting much simpler. For a professional all labels should be computer generated. Hand written labels are just not acceptable today. 

Network Cabling Installation

Network cabling installation drawings should be designed by a BICSI certified RCDD (Registered Communication Distribution Designer). There are a few things that need to be considered.

The type of cabling solution to be implemented - The cabling vendor or customer will need to select a solutions manufacturer. Siemon, Leviton, Ortronics and Panduit are some of the more common choices. The type of cabling solution will need to be discussed. Cat 5e, Cat 6, Cat 6A or Cat 7 are the copper types of network cables that can be offered. The style of the racks, data jacks, faceplates, patch panels and wire managers will also need to be discussed and chosen. Make sure this is done early as lead times can be long for certain manufactures and styles.

The location of the network equipment and racks - The room where they are housed is commonly referred to as MDF (Main Distribution Frame) Data Room, Telco Room or Telecommunications Room. All cables runs need to be within 100 meters. If cable runs are going to be over 100 meters you will need to add a second Telecommunications Room. This is also called an IDF(intermediate Distribution Frame). The IDF will often need to be connected to the MDF via fiber optic backbone cabling. The MDF will house the service provider feed from the street, which will feed the network. Typically you will also find security equipment and access control equipment here. It is a better design to have all the low voltage systems housed in one location. Measure all equipment and racks that will be required based on cabling quantities. Include access control, security, electrical panels and air conditioning units. The room needs to be large enough to accommodate all equipment.

The pathways of the cable trunks above the ceilings - Cable paths need to steer clear of electrical light fixtures or other sources of EMI (Electro Magnetic Interference). Keep cable paths in accessible areas of the ceiling for future cable runs and ease of maintenance. All paths should be run above hallways or corridors and cables enter individual rooms on sweeping 90 degree turns. Install a firestop sleeve or putty for all penetrations of a fire wall. Be careful when pulling cables so as not to bend them beyond their bend radius. This will cause a failure when testing. DO NOT tie cables to ceiling hangers or sprinkler pipes. They need to be tied at least every 5' on horizontal runs, and even more on vertical runs. J-hook supports should be anchored to the concrete deck above. Use velcro wraps every 5' or so when finished running cable to give your cable bundles a great looking finish.

Terminating Network Cabling - When terminating cable make sure to check the floor-plan numbering to each cable label to make sure the cables are in the correct spot. If something is not matching leave that cable on the side to be "toned out" later on. Use a cable stripping & cutting tool to get a uniform cut on the cable jacket and to be sure you won't nick the copper conductors inside. Always keep each pair twisted as tight as possible right up to the pins where you terminate the cable. This will ensure you won't get a NEXT or Return Loss failure. Before you start any terminations inquire weather the pinout will be 568A or 568B. This will determine which order the conductors are terminated in and is very important before you start. All cables should be dressed nicely and uniform. The project manager should make a termination chart of the patch panels for the technician that will perform the terminations. This will show the back of the patch panels and where each cable gets terminated with it's label number.

Testing your network cabling - There are a number of cabling testers out on the market. The tester we prefer to use is the Fluke DTX-1800 Cable Analyzer. This is an amazing tool. It will give you a detailed report of each cable that is tested. It tests for wiremap, insertion loss, NEXT, PSNEXT, ACR-N, Insertion Loss and many others. The best part about these new age testers is their troubleshooting skills. The Fluke will tell you where a cable is damaged and which particular conductor is damaged. If you terminated a pair out of sequence the tester will tell you which pair and on what end the error was made. The Fluke does everything but fix it for you! Most clients want to see verified test results. The new testers will provide cleaned up PDF files of the test results. These can be emailed directly to the client.

Hopefully this guide has helped you to better understand the complete system of network cabling. It is an ever changing field and we need to keep up on the latest technology to stay ahead of the curve and offer our clients the best cabling solutions. Please add your comments, suggestions or questions. Please sign up to our email list for the latest cabling news and our shared experiences from the field. You will also receive special offers on future training products before they are released. Thanks for your support.

I don't think the temperature is accurate on this monitor. The reason I bought it is because my room stays icy cold in the winter and hot in the summer--even though we have central air and heating and when I look at this monitor the temperature always feels lower than this monitor shows in my cold room. I can't prove this because I have no way of checking the monitor against something else. But I can hardly believe that the temp is warmer (showing on the monitor) than it actually is. It always feels about 10 degrees colder. Have not had summer weather yet, so I can't state how accurate it seems then. I think the humidity reading is probably right because where I live we have a lot of high humidity, and especially before it rains and during rain storms, and this monitor always shows high humidity when that happens. But I really wanted a monitor for the temperature reading, so this was a disappointment to me.
