One year ago, I tried various book catalog software, including Delicious Library, and ended on Booxter. One of the main reason, as a Norwegian citizen, was the many non-US sources Booxter search through, including two Norwegian ones. I hope even more sources are added in the future, especially an African one like e.g. the National Library of South Africa.

Otherwise I find Booxter a very straight-to-the-bone app that does cataloging and just that. It's not an app you fall in love with at first sight, but an app you like better the more books you add. As my library grows, I really appreciate the many good browsing options Booxter includes, like the tag view where you can browse the books by genre, publisher, year, Dewey class, subject, etc. Many fields are available, but some are missing like e.g. "Original title". But then there is of course a notes-field to enter misc info. The smart list feature is also really useful.

One quite serious issue is the documentation, which is almost non-existent. This is not acceptable for an $50 app. There are so many features in Booxter, some of which are quite hidden, so good documentation would be really useful for new users. Also, I've not received replies to my two emails to the developer.
