Calibre is a FREE & open-source suite of e-book software for multiple platforms (Windows, Mac/macOS, Linux). Calibre supports organizing existing e-books into virtual libraries, displaying, editing, creating and conversion of e-books, as well as syncing e-books with a variety of e-readers. Editing books is supported for EPUB and AZW3 formats. Books in other formats like MOBI must first be converted to those formats, if they are to be edited.

Calibre is a vibrant open-source community with half a dozen developers and many, many testers and bug reporters. It is used in over 200 countries and has been translated into a dozen different languages by volunteers. Calibre has become a comprehensive tool for the management of digital texts, allowing you to do whatever you could possibly imagine with your e-book library.

Calibre is a nice (and free!) tool for cataloging collections of ebooks. Lately I've been using it to organize a bunch of titles to load on my Amazon Fire tablet for reading.

The big think to keep in mind with Calibre is that updating the metadata doesn't update the actual book files, instead the metadata is stored in its own Calibre library file. If you update the metadata for a book then copy just the book files to a different location then the metadata doesn't copy with it, you need to either use Calibre to copy the book to a device or to copy the Calibre library.
