Tour: Pentagon Library

On the 21st of May 2014 a group of Library and Information Science students from the Catholic University of America, including myself, went on a tour of the Pentagon Library. Reader beware: there are no state secrets in this post, but, all the same, I hope you are able to learn something from this post and, one day, have the opportunity to visit the library yourself.


The Pentagon Library uses Library of Congress classification.  Within their library, they have small targeted collections such as Language Learning and Military Related Movies. Some of the major sections of the library include: Military Collection, General Collection, Reference, and Periodicals.  They also have a large amount of material on “Strategic Bombing Studies” as one of the librarians pointed out to us.  One of the librarians was very excited to have a bound copy of Reports upon the purchase, importation, and use of camels and dromedaries, to be employed for military purposes : according to act of Congress of March 1855 / made under the direction of the Secretary of War, 1855-56-57Their catalog is made publicly available here.


The mission of the library is to provide “a research capability to Department of Defense personnel working at the Pentagon and in the National Capital Region (NCR).” (About Your Pentagon Library)  As another Librarian put it “The point of what we do is to enable you to have the right information to make the right decision.”  What really makes the library work is the librarians who help the users navigate the information.

There are currently 18 library staff members that serve the Pentagon and the National Capital Region.

Brief History of Pentagon Library

The original library was the War Department Library established in Philedelphia in 1795. The Pentagon Library was established in 1944. After 9/11, the library was relocated up the road to Pentagon City.  It was moved into it’s current location in October of 2006. In 2007, the library governance was transferred to the Washington Headquarter Services.

The Pentagon Library is not financed through direct appropriations, but rather through a revolving fund that also pays for building maintenance according to one of the librarians who was describing library operations on our tour.  To get a Pentagon Library card you will need a building badge; sorry folks, they just don’t hand these things out (I asked).

Scope and Extent of Collection

The main focus of the collection is in the following areas: Military Arts and Science, Naval Science, Military History, Policy Making, International Law, Political Science, Leadership and Management, Law and Legislation, Organizational and Behavioral Psychology, Speech Writing and Training, Travel, and Foreign Languages. (About Your Pentagon Library)

There are approximately 200,000 items in the catalog and they subscribe to over 70 databases.  (Facts about the Pentagon Library) It is great to know that the Pentagon is well informed, and has access to the latest information, but more so that they have an experienced staff of information managers to help them dig into the research that they need.

With respect to their virtual services, the library has three objectives: 1.) Match user experience inside and out, 2.) knowledge management, and 3.) better statistics for better decision making.  To accomplish the first objective they utilize libguides, Ebsco Discovery Service, and EOS International.  The library has also conducted surveys to see how they can improve their services.

Military Documents

Military Documents have been generated for internal military use, many of which deal with policy. The system works similar to that of the FDLP, and series assignments are based on subjects.

Currently, the staff is working on digitizing the army reports. Once material is digitized and cataloged, the item becomes searchable in their catalog. There is a strong need for a larger digital repository with more server space to make the collection accessible online; just  because something is digital doesn’t mean it is necessarily easy to find.

More about the Pentagon

After feasting upon the richness of their collection the librarians that were our guide asked if we would like to go on an additional tour of the Pentagon (Sorry guys, no state secrets again- just highlights from the open air museum that serves as many of the corridors).  There are numerous exhibits that mark the hallways of the Pentagon. Some of the exhibits that are up this year include: “Army Strong: Strength of a National- War fighter Superiority, Net-Centric”,  The Five Conflicts Memorial ExhibitGlobal Mission 1942-1949, Women’s Military Corridor & Vietnam Women’s Memorial StatueNational POW/MIA Recognition Day Photos“Secretaries of War Portraits. Flags of 13 Original Colonies,” and “50th Anniversary of Integration of the Armed Services, 1998 Proclomation.

We were blessed to be able to see many of these exhibits.  Our guide led us towards an interactive display that is updated daily with photographs from around the world with high definition pictures.  Behind that particular display was a set of movie posters that the Pentagon had lent it’s expertise to. These films include Lone SurvivorCaptain America, and Godzilla.

Pentagon hallway

The hallways can be confusing as most of the passages look the overly similar: white ceilings with white floors and white walls broken up by the occasional locked door.  On the interior ring, there is an expansive view of the courtyard.  Our tour happened to coincide with DARPA day so their were tents up everywhere showing off various technological advancements and gadgets.  Our guide told us how one year during a celebration that the Pentagon was having they hired a local bakery to build a cup-cake tank, which sounded delicious.
