Calibre 9.0.0

Calibre is a digital book library management software for computers, free and open source, created to centralize and manage large collections of e-books in one place. The program's purpose is to facilitate control, organization, and access to digital books stored on the computer. Calibre allows you to catalog e-books in detail, creating customized virtual libraries. You can organize titles by author, series, publisher, language, publication date, or any other available criteria, as well as create collections and custom filters to quickly locate a specific book within the library. The program includes advanced metadata editing tools, allowing you to correct titles, author names, covers, descriptions, tags, and technical information of the files. It is also possible to automatically download metadata from online sources, ensuring that the library remains standardized and well organized. Another important feature is the conversion of digital book formats. Calibre can transform e-books between various compatible formats, adjusting structure, fonts, and layout for better reading on different devices. Supported formats include EPUB, MOBI, AZW, PDF, HTML, TXT, CBZ, and CBR, among others. Calibre also includes an integrated e-book reader, allowing you to open and read books directly in the program, with support for bookmarks, highlights, and chapter navigation. For those using e-readers, the software offers device management, making it easier to transfer books between the computer and compatible e-readers. The plugin system greatly expands Calibre's functionalities. Through extensions, you can add extra features, integrate the library with cloud storage services such as Dropbox, Google Drive, and Apple iCloud, as well as automate tasks and customize the program's behavior. There are also features aimed at integration with Amazon, such as sending books to Kindle devices and accessing catalog information. Being cross-platform, Calibre is available for Windows, macOS, and Linux, maintaining the same functions across all systems. The active development and the community constantly contribute improvements, fixes, and new features, making the software one of the most complete solutions for managing digital books on computers.
