This is a WordPress plugin I developed from scratch for cataloging and recording my personal library which has become pretty successful. The user can add a book by filling out a simple form. Once filled out, the plugin takes the ISBN number of the book and interfaces with the Amazon, Google Books, and OpenLibrary APIs to grab as much info about the book as possible, to include the cover image, number of pages, publication date and publisher, etc. Check it out here, and head over to the WordPress Plugin Repository to Download Your Free Copy of WordPress Book List. Also be sure to check out It’s stand-alone website where I sell Extension and Plugins at WPBookList.com.
