ZBar is great, but you will need do have optics on webcam that will make
barcode sharp enough to be reconizable. In my expirience, webcams rearly
have focus manipulation if they are built in laptops, and even external
open usually can't make sharp picture for anything which is closer than
30cm or so which makes picture too small.

I made even a small bounty among my friend to try different webcams, and
so far noone reported succesfull scan of barcode with webcam. YMMV.

I had better luck feeding zbar with pictures from digital camera, but my
best expirience is with zxing on cell phones, so you might take a look
at that option:

p.s. additional benefit of zxing is that it has support for codabar
which we have on our books, but that is specific for our library.
