When scanning in book mode with the 3600, how much time would it take for a 150 page book?
What is the optimal setup to use the OCR, and how precise is it?
Is the scanner efficient with lightweight paper backs without adding additional weights to the cover?

There are two issues here.
First, scanning time. If the book is small enough for a flat double page scan, I find it take around 30 seconds a double page scan. This depends on how fast you lift/turn page, and how certain you are ar getting the next pair of pages (you can accidentally skip page pairs if you aren't careful). At 150 pages, I'd recommend scanning in two blocks and later adding them together.
Second, OCR. Hardback OCR is roughly 99.5 percent accurate. This averages about 1 defect per page. It varies depending on the font and the cleanness of the page. Remember, you still have to go in and remove page numbers and page headings (if any), correct all OCR misreads and any incorrect paragraph breaks before you're done. This take 4-8 hours for 150 pages.
Forget paperback sources. They scan at 85-90 OCR accuracy, which means you might as well type them in. If you
must use a paperback source, try blowing them up to 11/17 (double page) at a commercial photocopy shop and scan the photocopies (one page folded per scan). It provides a larger size font and better contrast, increasing the OCR accuracy. So I have found.
