I don't think anyone's talked about this article, and I run the risk of being chased out of here, but when I saw this post I changed my book scanning process and it has been a dream: http://lifehacker.com/5785565/how-to-di ... rcular-saw
I don't actually use a circular saw, but rather I take the book to Kinkos. $2/book and I get the same result. I may get an industrial paper cutter I saw on Amazon, about $150, that does the same thing, the circular saw idea looks too messy.
But after cutting off the edge, I run it through an industrial scanner I have access to and I can pdf the entire book in about 3-5 minutes, and the output is beautiful. The ocr'd result are much more accurate than what I was getting w/ my original scanner. The only problem is that it's destructive.
In general, I prefer to buy my ebooks (kindle). So the only books I scan are out of print, which I get dirt cheap from used book stores. Thus, since they're already out of print, I figure destroying one copy to preserve it digitally is worth the loss.
Anyone else out there using a similar work flow?
