With my recent conquest of development software, (specifically Symantec C++ and THINK Pascal.) I thought it would be useful for me and others if I try to "bookscan" their programming manuals. 
I plan on using this Instrucable to create my "book scanner." The results are actually quite good.
I put together a little sample PDF of THINK Pascal's User Manual. But I didn't have the tripod setup so some pages are too small, warped, etc.
Once I setup a proper place to do it, I'll be working on "book scanning" the following:
THINK Pascal:
User Manual (Image scan complete, prepping pages for PDF.)
Object-Orientated Programming Manual
Symantec C++:
Compiler Guide
Visual Architect and THINK Class Library Guide
Turns out there were PDFs of these on Symantec's C++ 8.6 CD: Download them here.
I plan on eventually book scanning the following: (these are not as scarce, so help preserve and get the real book from thiftbooks.com or amazon.com!)
Macintosh Pascal Programming Primer vol. 1: Inside the toolbox with THINK Pascal by Dave Mark & Cartwright Reed
Foundations of Mac Programming by Dan Parks Sydow
I might do some other general programming books I have. But the priority are the four programming manuals.
Format: Final results will be PDF. However I have been looking at the Djvu format. Apparently there was a Browser plugin made for Mac OS 9. And DjVuLibre can convert Djvu to PDF. So I would be able to provide both formats. 
Current Status:
I am currently in the process of prepping the pages for "THINK Pascal: User Manual."

I'll get them uploaded by tomorrow.
