Booknizer is a comprehensive utility designed to help you keep your e-book collection neatly organized and documented. It not only interacts seamlessly with the most popular e-book readers in the market – including, but not limited to, Kindle, Nook, and Sony Reader – but it also allows you to download and append useful information about your favorite authors and books.

It comes with all the features you need to organize your entire collection, regardless of its size and complexity. You can combine the books in your favorite devices with folders of e-books stored on your computer, and classify them by author, title, subject, language, etc. It allows you transfer books from one device to another or from your computer to your e-book reader, converting the books selected into the format required by the importing device and keeping your different locations always synchronized. Some of the e-book types supported are EPUB, MOBI, PRC, FB2, and PDF. Additionally, Booknizer can also deal with your audio book collection, supporting books in MP3, M4B, and WMA, among other audio file formats.

To make browsing your library a more attractive and inspiring activity, Booknizer allows you to document your books fully by adding both personal comments and ratings, and a plethora of interesting information about the books and their authors. This information can be easily downloaded from Amazon or Barnes and Noble (among others), complete with book covers, authors’ photographs, etc.

Booknizer comes with a long list of other useful and simple features, such as a loan manager to help you keep track of all your books, a built-in audio player to listen to your audio books, a set of visual reports and statistics, or the possibility of locking up your database using a password.
