Civil War Records Common to all Regiments

The Cemetery Index and Graves Registration (Cards)
The result of a WPA Project conducted during the 1930's to locate and plot each veteran's grave. Cards are filed alphabetically by each soldier's name. Records are incomplete and many inaccuracies have been noted.
Muster Rolls
Muster-In Rolls, Descriptive Rolls, Monthly Returns and Muster-Out Rolls of each Regiment. Bound and encapsulated in such a way that they cannot be photocopied. Related to them is the Soldiers' Index, a 3x5 card file for each soldier, on which all information from the Regimental Rolls has been abstracted. The Adjutant General's Office also tried to maintain a separate index for seamen, but it is very incomplete. The "obituaries" are a file of newspaper clippings or other memorials regarding the death of Maine veterans; it is very incomplete as are the General Law Pension records.

Civil War Records Unique to Each Regiment

The clothing books are simply a register of each item of clothing issued to a recruit. The Post Office Addresses are the result of a late 19th century-early 20th century effort by the Adjutant General's Office to keep track of all surviving veterans. It seems to have been maintained until about 1920, and is very incomplete. Also included in this category are gift items.
