[iBook] Off topic? Audio and OCR help wanted

Joe is correct. Text can be present in a pdf either as text, or as an image
(imaging taking a photo of a page, and putting a jpg of that in a pdf). In the
case that the text is stored as an image, you cannot use the text tool to
select and copy the text. You will need to use OCR.

Can't suggest a program, but a quick google shows two GNU OCR packages (these
are Free Software).
These might not be particularly user-friendly - especially on Mac.. you might
need to shell out some $$$.

Have fun!
