scanning a ton of documentation

Hello, The person that refered me to my present job at a datacenter passed away this past monday. He was a hardware / software engineer for modcomp computers. He left me all of the computers and documents. there are too many books to keep, stuff concerning the modcomp computers that is not saved anywhere else that i can tell. I have picked up storage containers for all the books, and i can scan it all. after that, its all probally going in the recycle bin, as i dont know where or how i would keep such a large pile of paper manuals on hand. what is the prefered format to upload things to bitsavers in? is pdf acceptable? How can i create a pdf that is not too big on file size? Can the text be recognized and be made searchable within the scanned pdf? any input would be appreciated, Thanks. --Devin D.
