The bulk of the collection contains rosters of Michigan veterans from the Revolutionary War to World War I. Also included are rosters of Military units formed in Grand Rapids for service in the Mexican War through World War I. Of special interest are the rosters of the four Michigan regiments, by company, that served in the Spanish American War. Also included are unit rosters for medical unit Q, 339th Ambulance Co., and the Polar Bears, of the 85th Infantry for World War I.

For further information on the Polar Bears see collections #23 and #33, and/or 339th Ambulance Co. see collection #108. Hall's list of Kent County men in the Civil War was given to the State Library of Michigan, which returned it in 1979. This list was processed as a manuscript collection #144 Kent County Civil War Men. The Hall collection of obituaries typed and transcribed from various state newspapers has been used as a reference work by the Local Historical Collections staff.
