I wish I had the $$$ to shell for good OCRware, but in my informal tests of OCR:
Microsoft One Note OCR > OCR PDF from an industrial multipurpose office copier > cheap OCR Abby Finereader lite that came with a desktop Epson Scanner
I also looked into tesseract and some of the other open source stuff.
I like the idea of a
DIY Bookscanner as a digital camera is always handy and available.
But in the end, convenience (laziness) wins out and we still just buy books.
This scanning business is good for rare works like time limited reserves or archival library journals. It reminds me of old school days (pre-WWW) when I met a 'professional scanner' who came with sunglasses and could work the university copiers like an orchestrated ballet. His ninja timing was so perfect he knew the flashing scan registers for all the different models.
Humans, still good fer sumpthin
