Greetings James, Greg, Al, et al., Now that there's a lull in the traffic, I'd like to introduce myself. I'm Ray Puzio and, over the years, I've been active at PlanetMath, which is a free online math library. Now that we've redone our software, one of the things we are working on is adding public domain math books to our offerings. For instance, here is a copy of Brenke and Davis' calculus textbook : http://planetmath.org/node/87448 (Only the first five chapters are currently available since I haven't finished proofing the rest of the book against the scans. (The full version will (hopefully) be ready in a few weeks.)) In connection with this, there were two questions I would like to ask you all. Firstly, we were thinking of adding some PG books to our collection (a few textbooks at first, but later other math books). While, of course, this can be done without asking because the copyrights have expired, out of courtesy and respect we would like to thank you for your hard work. Looking back in the list archives, I saw a post by Lee Passey on 3 March 2012 which addresses this point. Based on that post, I was thinking to do this by attaching a note like this: | This edition was derived from the Project Gutenberg edition [EBook #??] | last edited ????. That edition was produced by ????, ????, and other | anonymous volunteers. | | This edition was edited by PlanetMath and equipped with metadata in order | to accommodate the format of our collection. Does this sound good to you or would you suggest some other way? Secondly, as long we are are digitizing old books like the calculus text above, I would also like to submit them to PG. Especially after reading in the list archives about how the documentation isn't always accurate, how there are unwritten rules, etc., I would appreciate if someone experienced could help guide me through the process of going from a LaTeX file to a PG e-book. Yours Truly, Raymond Puzio Operations Manager PlanetMath.org
