calibre 2.39.0

Update after update, calibre still remains as the reference in its class. Far from being a simple e-book manager or a virtual e-book library, this open-source tool is an integral e-book management tool with a set of extra utilities that, in some cases, are full software applications in their own right. Thus, its e-book viewer is actually a full-featured e-book reader, and its e-book editor is a full-blown EPUB and AZW editing tool. This is the added value that makes calibre stand out and above all its competitors.

You can add e-books in any conceivable format to your Calibre Library, and even have the same e-book in various formats neatly grouped in one single record of your catalog. calibre gives metadata the importance that it has always had in the library world – unlike other e-book managers, calibre allows you to add extensive and useful information to your e-books, and helps you find it in case it is not present on your file. Metadata is what gives sense to a book collection – to any collection, for that matter – and what allows for accurate searches and neatly organized lists.

Adding books to your library is extremely easy – calibre will allow you to add e-books in nearly all known formats, including standard Office documents and TXT files. These simple documents can be easily converted into full-featured e-books (say, in the EPUB format) using the program’s e-book conversion tool. This utility, far from being a simplistic format-to-format converter, can be fully customized to produce e-books with the level of quality that e-book lovers require. From metadata to page layout and from tables of contents to automatic error fixing through heuristic processing, calibre’s converter can be designed to produce excellent e-books in the most widely used standards. If anything fails, you can always rely on the program’s editor for EPUB and AZW e-books, and fine-tune any error left behind by the conversion process.

calibre comes with its own “e-book viewer”, a comprehensive e-book reader that allows you to change the font size, read your book in full-screen mode, move to the table of contents with just one click, jump from page to page, add bookmarks, see the text in reflowable mode, print it, etc.

Regardless of your specific needs when it comes to e-book management, calibre has all the possible answers to all your questions. For many years, it has been the reference in this field, and that includes not only other free open-source developments, but most commercial tools designed to help you organize your e-book collection.
