At the risk of coming into the middle: My experience is that the time consuming part of going from book to E-book is the proofreading. The scanning, cropping, and OCR are probably less than about a quarter of the time. - I use a Canon S230 3 megapixel camera in a copy stand to get about 300 dpi scans. I can do 4-6 pages a minute, without destroying the book. I have been quite happy with using a camera as scanner, but 600 dpi would halve the processing speed. I tried 2 pictures per page, but I did not find any improvement in the OCR quality. - I use Abby FineReader 5.0, which was not that expensive, and it usually finds the right text, flipping pages and cropping automatically. A pass over the pages using FineReader to find basic OCR issues takes about 15 seconds a page. So up to this point, a 250 page book could be done in 2-3 hours of concentrated work. I would guess I have 2-4 errors per page at this point. - then comes a first pass proofreading, also fixing headers and footers. this is often 30 seconds per page. - then a full second pass of proofreading, again about 30 seconds a page. I probably find an error a page in this pass. Then I ship it. I could believe it could be done in a day's elapsed time, but I don't think I can focus that hard all in a single day. The real problem is my day job is using up most of my available concentration, so I don't feel up to spending too much time proofing. my 2 cents... Kent Fielden
