While The American Legion is not a government office, staff can refer inquiries about military records to the appropriate government agencies. However, National Headquarters cannot intervene on any individual’s behalf in this process. (The appropriate channel for help on benefits and claims is the Legion’s corps of department service officers.) Questions on military and U.S. history can sometimes be answered, but because of the volume of letters and office deadlines, referral to other agencies, such as the U.S. Army Military History Institute, may be necessary.

On a limited basis, The American Legion Library's staff can help with locating former military comrades by forwarding mail to Legionnaires. However, there are no service numbers or Social Security numbers on Legion members’ records to positively identify individuals. The library staff also handles most of the organization’s microfilming requirements. A microfilm reader/printer and a photocopier are available in the library. The cost of a copy is 25 cents per page.

The office of the national historian is also located in the library. While the national historian spends most of the year in his or her home state, correspondence and matters of post and department histories are handled in Indianapolis. Each year during the week of the National Executive Committee meetings in October, the national historian oversees the judging of the national department and post history contests.

Those interested in writing resolutions or reports can find help in the following guide. Print it out, if needed, or contact the library for a printed copy.
