Thanks for the hardware tip, but I do already have a scanner with auto document feeder and auto duplex, but did not want to destroy any books.
With ReadIris Pro, how often do you find it has errors in the OCR, and does it handle pictures and diagrams on the pages well? Does it always give an exact copy of the original when you convert to PDF with the same fonts and everything?
I have read reviews on the 3 main pieces of software above and different reviews have different opinions - some love one program, others hate it with a passion. ReadIris on the Mac at least is a total nightmare and patches from company impossible to get from them. OmniPage apparently used to be the best a few years ago as it has a long history but current status is hard to fathom. Equivalent versions of all 3 packages have approx the same price. So it is quite confusing.
