Those are the easiest, since there are no drivers involved :). The
keyboard variety are very easy to integrate with a web-based form.
As a side note, you can also get magstripe readers that work in a similar
fashion, interfacing with the keyboard, and you can even get keyboards
with the reader built-in.

If you're using a basic 3 of 9 (code 39) barcode, you can do it with a
truetype font in your favorite word processor.

I believe on books, the EAN/UPC code actually *is* the ISBN number, plus
the extra 5 digits at the end indicating list price.
For example,
"A Practical Guide: Unix System V, 3rd edition", by Mark Sobell, has an
ISBN of 0-8053-7566-X. The EAN code reads: 9-780805-375664-53795. One can
clearly see the ISBN embedded in the EAN.
Another:
"Forgotten English", by Jeffrey Kacirk, ISBN 0-688-16636-9 has an EAN of
9-780688-166366-90000. I'm not sure how the last character of the ISBN and
the EAN translate out, they may be irrelevant.

You could always have a perl script query a web database of ISBN numbers
(for example, amazon) and populate the DB with that info as well
