Hi, Fergie-

Mudcat's Dick Greenhaus has done some first-rate reissues, most notably Sharp and Bronson. They're being marketed through Loomis House Press. I can't find Dick's CAMSCO Website, so maybe he's closed that down. Send Dick a personal message and ask him how he did it.
The Sharp and Bronson books are absolutely terrific. I think they're mostly scans of the original books, but they are very high-quality reproductions.

The Mystic Seaport Museum did an abridged reissue of Stan Hugill's Shanties from the Seven Seas. Hugill used kind of an unusual font for the music notation and first verse of every song. It was hard to read in the original, but impossible to read in the reissue. I finally gave up and bought a used copy of the original. Lesson: you can't reproduce every book by photographic means.
