Calibre is a free e-books library program to manage your readings.

In other words, you could say Calibre is to e-books what iTunes is to music.

Calibre can even download news from certain webpages or RSS feeds and convert them into e-book content. This can be done with online newspapers like The New York Times, The Wall Street Journal, The Economist or The Guardian. As well as that, Calibre has a content server that provides online access to your collection no matter which computer you are using. This server is compatible with smartphones too.

How does it work?

When it comes to library management, Calibre can sort the books by Title, Author, Date Published, Date Added, Series, Size or Rating, among others. In addition, it is able to search for extra metadata such as tags, to categorize your collection, or comments. You can also take advantage of the Advanced Search. Regarding conversion capabilities, Calibre supports a wide variety of formats and always respects formatting to obtain a readable and visually attractive output. It can rescale font sizes or detect the book's structure.

Syncing your device with Calibre is very simple. In fact, you won’t have to worry about formatting. If a book has several formats available, Calibre will choose the best one to upload it in to the e-reader. If none of the formats are compatible with the device, the program will automatically convert the e-book to a suitable one before sending it.

Calibre has keyboard shortcuts to offer a faster experience when it comes to performing the most important functions. With the "D" key you can send the books you have selected to the device you previously connected to the computer. Conversion can be started by pressing "C" key; and if you want to read the book on your PC, then press "V".
