I work in the IT department for Quality Books Inc, a small press book vendor
for public and school libraries. We have a growing number of customers who are
utilizing Evergreen. As a book seller, we are always interested in trying to
avoid selling a book to a library that the library already holds, which then
usually leads to a return of the book to us. My question is this: is there
available in Evergreen a web service or custom URL string that would allow
asking for the existence of a book in a library's holdings (using ISBN as the
book identifier)?
Thanks.
