Hi, Judy. Each publisher does their books a little differently, so all I can really offer are broad generalizations. For the quality of print, I like hardcover or standard paperback editions. Publishers tend to use better paper and ink in the hardcover editions of books. Standard paperbacks work well for me too. Mass market paperbacks tend to have the worst quality in terms of ink and contrast with the paper. Their ink tends to fade and smudge over time, and their paper begins to turn yellow. That doesn't mean they can't be scanned though. I know several people who scan almost exclusively from mass market paperbacks. They take more skill and attention though. I wouldn't suggest them for a brand new volunteer to start learning to scan from. Paperbacks are physically easier to scan since they are more flexible and can be made to lie flat for scanning in two-page mode. If the person processing your books is using either an OpticBook or a document feeder, the flexibility of the book won't matter though. I hope this helps. -- Monica Willyard Visit my blog at http://www.scannersguild.com To unsubscribe from this list send a blank Email to bksvol-discuss-request@xxxxxxxxxxxxx put the word 'unsubscribe' by itself in the subject line.
