I used this component for a lending library, and purchased the pro version because I wanted multiple categories. I was able to configure most of it to suit my client's requirements, but did need a couple of fields added in the lend request form, which the Ordasoft team took care of very promptly and effectively. Support was always first class. The ISBN feature is invaluable, instantly bringing in all the relevant information. My server does not provide the PHP YAZ extension, so I could only search Amazon (as in the Basic version) for old ISBNs. However googling, copying and pasting worked ok for the few I couldn't do automatically. I'm VERY happy with this extension, and my client is delighted! What I would like to see is a way for the client to review lend requests from the front end. Congratulations to the Ordasoft team for a great extension.
