I'll be scanning and posting some more 77-91 service manuals over my Christmas '12 vacation.
I've found some specialized unit repair booklets, tech training booklets, and 67-71 10-60 series service and overhaul manuals to scan as well. The 67-72 manuals will prolly wait till the square stuff is scanned.
If anyone has the foldout ST352-81, ST352-82, or ST-352-84 wiring manuals and would be willing to let me scan them PM me. If you're in NH, RI, or Eastern MA I can meet you. I will have to CAREFULLY remove all three binding staples to run the pages through the scanner. My manuals are as original now with the exception of some brandy new staples.
I guillotine the binding glue off the service and unit manuals. So I'm only scanning manuals that are in kinda tough shape to start with. They are complete but the covers and first few pages are generally loose or barely hanging on and some have some truly impressive dog ears to fold out and press/iron flat enough to carefully feed through the scanner.
For anyone who cares about this kinda stuff...
I'm scanning these as text-under-image searchable PDF files. What you see is the original image complete with tables and proper formatting. This method uses OCR text for text searches and cut-n-paste operations. Otherwise it's hidden... as are any errors in the transcription.
I use a Fujitsu FI5530C2 sheet-feed scanner using 400x400 dpi greyscale with modified brightness and contrast settings.
Software is GIMP for long sheet wiring diagram bitmap image splicing, ABYY Finereader 11pro for OCR, and Acrobat 9 for final PDF optimization.
