In all my time on Bookmooch, i've had problems with Bookmooch's way of handling titles. If you add a specific edition of a book, it can happen that other versions of those books don't appear as moochable, even if it's basically the same book (just another version).

Now, I found a way around that. I imported my entire wishlist into Librarything and then set one of my columns there to show which of those books are available on Bookmooch. All of a sudden I found out that quite a lot of books that have been on my wishlist for years are actually available. Contrary to BookMooch, Librarything doesn't make any distinction between language (which is annoying), but also not between editions. You get to see all the versions that are available to mooch!

People with a Librarything-account should try it. For me, it was a reason to not longer update my wishlist on Bookmooch. I keep everything up-to-date on Librarything now.
