now that I work in library software :)  ...

Fetch data from ISBN is not so difficult, depends on the provider you want.
The most used protocol around the world is Z39.50
http://en.wikipedia.org/wiki/Z39.50 to get MARC formatted catalogs
http://en.wikipedia.org/wiki/UNIMARC.  I don't know if there's Smalltalk
implementations of these standards.

If you don't need high level of details, Amazon, Library Thing, ... have
good catalogs with modern web services to access them.

For the webcam / scan part, I don't know what we have in Smalltalk.  You
need OCR tools...
