GDG- "Gettysburg Sources" (James McLean)

[Todd Estabrooks]

I have recently found references to a work called "Gettysburg Sources",
puslished by Butternut and Blue some years ago. Basically, I had some
questions about the work. First, is the work a collection of first-hand
accounts? If so, does it share any accounts with the Bachelder Papers or
Gettysburg Papers (published by Morningside)? About how long is each volume
of "Gettysburg Sources"? Finally, how does "Gettysburg Sources" compare with
"Gettysburg Papers"?

Any info along these lines would help.

Thanks.
