I have a hunch about what went wrong with this book. This applies to
both Openbook and Kurzweil. Do you ever notice that during a scan
that your scanner will make a sort of stuttering sound, almost like
it's recalibrating itself and that that specific page takes a little
longer to scan? My scanner does this maybe once every 70 pages or
so. When it does this, I've noticed that the page it scans ends up
being totally garbled. In fact, when I hear that sort of stuttery
sound, I pick up the book and let the scanner do it's thing. That
results in a blank page that I can easily remove. Then I put the
book back on the glass and keep moving along. I learned this by
trial and error because it's one of those little things that isn't
written down anywhere.

Next, before I scan, I turn to a page well into the book and use the
optimize scan feature of Kurzweil. It usually does a good job of
adjusting the brightness setting and such. That starts things off on
the right foot.
The other thing I do once a book is scanned and before I submit it is
to run the rank spelling tool under the tools menu. If it finds some
really strange errors, or if it says my book is at only 96 or 97
percent accuracy, I know there's a good chance there is at least one
badly garbled page. I play detective and go hunting for that page,
using the page down key and read a bit from the top of each page till
I find it.
I hope I've written something here that can be useful to someone. No
one knows how to get a good scan until they've experimented and asked
questions. If each of us teaches someone else, we make Bookshare a
better place and improve the quality of the books in the
collection. So if anything I've written here isn't clear or is
wrong, please speak up. (smile)
