I stumbled on a reference to this company, 1DollarScan that offers a service to take your paper book and scan it to a PDF. Don't know anything about them. Was wondering if anyone has used them. Seems to have popped up last summer. They will take your books and slice off the spine and scan the pages into a PDF. Looks like you can pay a little extra and have an index of the text created. Cost is $1/100 pages. The files are quite large, 400 pages could be 80-160 MB.
They will destroy the book once it is scanned. It looks like that is the way they are getting around the copyright issues.
Looks like a clever way to make some shelf space - now if PDF's could be brought into Logos that would be great.
