Install and setup this highly regarded e-book management tool on your computer, and you can easily organize electronically formatted books into collections and read chosen publications with a built-in reader.

Since the electronic book market exploded due to the proliferation of mobile devices, keen readers have developed burgeoning libraries of novels and recipe books, non-fiction publications and self-help guides. The various e-book formats have penetrated our group consciousness to the point that readers are found within major bookstores and websites sell as many virtual copies of their paperbacks as physical copies. While this growing dominance is good news for the digitally-minded readers among us, there are new issues to contend with. Organizing this digital library is a chore, one that Calibre solves with a wealth of organizational features focused on centralizing the dizzying array of digital formats under one easy to manage interface. Calibre achieves this management with cool poise, creating a default library folder and allowing users to add extra libraries for different categories. Imagine setting up a category for Romance novels and another for non-fiction.

The software is free to use, open-source and available in a number of languages, making it extremely user-friendly. A Quick-Start Guide and video links ease the transition from physical books to the digital medium, and the software learning curve is very favorable for all users regardless of computer know-how. The management features include batch converting between popular file formats, renaming of e-books, the adding of cover images and much more. The navigation aspect has the potential to be complicated, but software developers have kept everything streamlined, delivering lists of managed books in several intuitive panes. The software guide sets up the interface for specific e-readers, an extremely handy feature, and makes the initial library setup a breeze. Set up the destination folder for the library and add books from any number of different sources.
