Research and Inquiries
The U.S. Army Military History Institute

In an effort to ensure continued compliance with regulatory requirements we are conducting a review of our collections prior to public release. These reviews may delay and limit some customer access to select holdings. We recommend that you plan your research trip to the U.S. Army Heritage and Education Center accordingly. Please call our reference team at 717-245-3949 for more information.

The USAHEC Military History Research Catalog/Army Heritage Collections Online will be unavailable to researchers 14-16 July 2014. Content saved to MyLists will not be accessible during this time, so please plan accordingly. Questions can be directed to the Ridgway Hall Reference Desk at 717-245-3949.

From July 22 to July 25, 2014, Ridgway Hall Reference Room services and support may be limited. Researchers planning to visit the USAHEC between 22 and 25 July should call the Reference Desk at 717-245-3949 (Mon thru Sat, 1000-1700) for details and advice.

The USAHEC's Military History Institute (MHI) provides researchers with professional direction and assistance identifying and accessing the Center’s resources and services. As an Institute of the U.S. Army, highest priority is given to U.S. Army users, but unofficial visitors and researchers are welcome to utilize the collections. Our on-site and off-site services for patrons are summarized below.

Research the USAHEC Archival Collections

The MHI is here to help researchers. New researchers are given a short briefing on their handling and care of our library and archival holdings, and are registered before materials can be accessed. The USAHEC is a "closed-stack" facility; our staff will retrieve the holdings you would like to use. There are no set "pull times" for requesting holdings; researchers can request additional materials at any time during normal business hours. However, only one cartload of materials per researcher will be allowed on the floor at one time. A member of our staff is on hand at the Reference Desk in the Research Room to advise researchers of relevant holdings available. The Institute also maintains a small but highly specialized reference collection in the Research Room that is readily available for use.


Research the USAHEC Online Archival Collections

In addition to digitized materials, the MHI has developed extensive online finding aids providing references to our entire collection, including over 8,200 reference bibliographies. To view these bibliographies and to search our online catalog for books, manuscripts, photograph collections, serials, microfilm, digital documents, and more, visit the Army Heritage Collection Online. The bibliographies, databases, and other resources found there will give you a good idea as to whether or not the Institute has research materials relevant to your search.

While physically visiting the USAHEC's collections is required to access most materials, there is a significant volume of historic manuscripts and photographs available online. Please visit the Photographic Holdings page for more information about researching our image collections.



Official and Unofficial Inquiries


or mail an inquiry to:
U.S. Army Military History Institute
Attn: MHI
950 Soldiers Drive
Carlisle, PA 17013

The MHI welcomes inquiries from official and unofficial patrons; however, the USAHEC does not perform in-depth research. We provide reference information about our holdings and can sometimes look in a specific source identified by a requestor, but we are not resourced to do more. We receive and answer tens of thousands of inquiries during the course of a year. Our staff is small and the workload increases with each passing year. Official inquiries take precedence.

If you wish to make an official inquiry (you must be a member of a federal government agency), please call the Military History Institute.

Unofficial patrons may submit an unofficial inquiry or also hire an on-site researcher by contacting the Army Heritage Center Foundation.

You are urged to review the list of Frequently Asked Questions as it may answer many of the questions you have regarding information available at the USAHEC and elsewhere.


Copies and Reproduction

The MHI offers several methods for reproducing materials on site. Copies of most books, manuscripts, microforms, and photographs in the U.S. Army Military History Institute can be provided for a fee. All reproduction orders placed by the public must be prepaid by check or money order and made payable to the “MHI Fund.” Payment cannot be made with cash, stamps or checks drawn on foreign banks. Payment for foreign patrons must be made using U.S. currency and in a form that will clear through U.S. banks. Patrons who have checks returned for insufficient funds will be charged a $25.00 processing fee in addition to the cost of the original order.
