To Kris Zapalac, Alan Rudrum, and Imagelib list members,The questions about scanners is unclear. Are you talking about converting text via Optical Character Recognition? If so, that is a different problem than simply capturing text with a scanner, which is an image capture only. I am assuming that you're talking about OCR conversion, since there are many image scanners on the market able to handle text (RLG recommendations are image capture at 600 dots per inch as a minimum for preservation-level imaging). If so, I doubt if any hand-held scanner would be able to capture the material in sufficient detail to permit OCR, but I have not had recent experience with one. It is tedious, at best, from our experience, and not reliable even for modern text--but this was about three years ago.
If I read the messages too quickly and missed some point, I apologize. I assume others will also be responding to these queries.
