I haven't had it fail once and I use it constantly: I've actually used to add edition I know aren't in the DB before I put the ISBN number in. Correction: I have had it fail twice with ebooks... I wonder if that's because they're using Amazon and relying on the ASINs (although I know Amazon stores ISBN information).

Amazon wouldn't store ISBN's for epub books though since they don't list those titles. I'll keep an eye on it, but I'm pretty sure it's happened to me for print books too. Maybe you just tend to search for more popular editions?

I'll grant you it working 8/10 times. I didn't mean that I could never find the book, just that it didn't always come up. When I then search by title, it's usually in the list somewhere, so it's fairly easy to add an edition from there. I wish you could see the ISBN when switching editions on your shelves though.

Oh god, so do I. I have asked for it and begged for it. But BL either doesn't think it's necessary, or it's planned for the mythical New Site.

I've figured out why they don't combine: BL will automatically combine two titles that are *exactly* the same AND have the exact same authors. That means because of the addition of the narrator, the audio doesn't combine with the rest of the titles. This also holds with editions that have illustrators, contributors, etc. It's especially cumbersome with older works that have lots of newer "special" editions.

Let the librarians know (or just me) which titles don't come up by search, if you'd like to, and we can check them out: oftentimes it's just a set of editions that need to be combined together. I try to search through the database, looking for things that need combining, but sometimes I'm flying a bit blind. :)
