I tested with a USB handheld cam and found it was just taking too long for
the capture (distance, light angle etc..) We have a few 1000 books to scan
and therefore the $30.00 scanner made sense.
With the scanner we can scan as fast we can pick up books into a doc and
then import into tellico, works like a charm.
