December 21, 2025 | Author: Maria Lin

Booknizer is a book organizer that works with paper, e-books (EPUB, MOBI, PRC, PDF, FB2) and audiobooks (MP3, M4b, WMA, etc.). It lets you copy books to a reading device (Kindle, Barnes & Noble Nook, Sony Reader, etc.), scan folders on your computer, search and filter book list and convert some e-book formats. For paper books, the program shows the exact location of any book on a bookshelf. The book organizer displays the book cover, synopsis, genres, publication year, as well as your own rating and comments. The program also allows you to view the author's bibliography, bio, and photos.

Calibre

Calibre is a free, open-source program (written in Python) for managing e-book libraries on Windows, Mac and Linux. It offers the most rich set of features, divided into the following main categories: library management, e-book conversion, synchronization with e-readers, downloading news from the internet and converting them to e-book formats, e-book viewer-reader, e-book editor and a content server for web access to your book collection. The program reorganizes book files into own structure. There are numerous plugins developed for the program by the community. However, many find the interface cluttered and unwieldy.
