Managing Your E-Book Library With Calibre

If you have accumulated e-books from multiple sources — purchases, free downloads, personal documents — they are probably scattered across different formats and folders. Calibre solves this by giving you a single organized library with powerful tools for managing, converting, and reading your collection. ### What Calibre Does **Library management:** Import e-books from any source and organize them by author, series, tags, publisher, and custom metadata. Calibre fetches cover art and metadata automatically from online sources. **Format conversion:** Convert between EPUB, MOBI, AZW3, PDF, HTML, and many other formats. This is essential for sending books to e-readers that only support specific formats. **E-book editing:** Edit the content and metadata of EPUB files directly within Calibre. **Content server:** Calibre includes a built-in web server that lets you browse and download your library from any browser on your local network — or remotely with some configuration. **News download:** Calibre can download news from hundreds of sources and convert it into an e-book for offline reading on your device. ### Sending Books to Your E-Reader Calibre connects directly to Kindle, Kobo, and other e-readers via USB. It can convert and send books in the correct format automatically. ### Why It Matters E-books are often locked to specific platforms or formats. Calibre gives you the tools to own your library in a format-agnostic way, independent of any single store or device. **For anyone with more than a handful of e-books, Calibre is an essential tool.**
