I have a photocopy of a Civil War Muster Roll which I am not sure where I got so I am having trouble with how to write the source citation. The document looks like a photocopy of a ledger book, with the names of those mustering in to Company A 87th Illinois Volunteers.
I know that I made this photocopy from the original book, I just don't remember if I did it in Salt Lake City at the library or in Illinois at the state archives. I did it way back in the early 90s when I first started researching and did not write down any source information.
I would appreciate suggestions on how to write a source citation for this document. Thank you!
