2023. Calibre 7.0 adds innovative notes feature, audio EPUB support



Kovid Goyal, the mastermind behind the wildly ingenious Calibre, has dropped Calibre 7.0 into the digital ether—a new stable version of the much-beloved, cross-platform, open-source e-book organizer that has kept readers and their libraries in delightfully structured chaos. In this spectacularly brainy update, users now have the thoroughly useful ability to attach notes festooned with links, images, and whimsically formatted text to authors, series, publishers, and tags. But wait, there’s more! Calibre 7.0 boldly steps into the sonic unknown with "Audio EPUB" books, where text is read aloud by recorded voices—though Linux users may encounter a small, patent-induced hiccup on that front. And, for a finale that would make even the most bureaucratically inclined Vogon swoon, the update finally answers long-standing pleas by allowing "data" files to tag along with your books, managed with a simple, glorious right-click. Revolution, thy name is Calibre 7.0.

The search now ignores soft hyphens when extracting searchable text from books (though you will have to re-index your library to take advantage of this). The e-book viewer now allows searching for nearby words using a new "Nearby words" search mode. New fts_search and fts_index commands allow to perform full text searching from the command line.


2022. Calibre 6.0 now has text to speech and full text search

Another significant new feature is Read Aloud, which will use your computer's default voice assistant to read any ebook in your collection. This includes Google Assistant, Siri, Alexa and Cortana. You can even adjust the playback speed for those who prefer to speed it up or slow it down. Calibre also now supports CPU architectures, including Apple Silicon, without the need for Rosetta translation. This is a major enhancement, as the app is now optimized for the M1 and M2 chips in Apple laptops and Apple Studio computers.

All highlights can be both stored in EPUB files for easy sharing and centrally in the calibre library for easy browsing. Additionally, the E-book viewer now supports both vertical and right-to-left text. calibre has also moved to using Python 3. This is because Python 2 was end-of-lifed this year. This should be completely transparent to calibre users, the only caveat being that some third party calibre plugins have not yet been ported to Python 3 and therefore will not work in calibre 5


2019. Calibre 4.0 improves Content server

The mark appears as a small pushpin icon next to the book and all marks are automatically cleared when Calibre is restarted.


2013. Calibre 1.0 is available for download



WoW! Seven years after it was first released, the free ebook management software Calibre has reached version 1.0.

2013. Calibre Server - access your book collection via the Internet



Probably you didn't know it, but Calibre includes the inbuilt web server - Calibre Content Server for remote library management. Besides it can download and send you the books by email. The Calibre server makes your ebooks available to the gadgets within your home or office wireless network. And if you can set up port forwarding on your router - you access your library from a remote location. You can set a password to restrict access. By default access is unrestricted. The content server lets you see the whole Calibre database on your device, which is great, although if you have a lot of books in your library - it can be slow and you have to keep hitting the “Next” button to advance to the next group of books hour after hour. Using this approach you are using the device to choose the books to download. This approach is effective if you’re just browsing your Calibre database looking for a book to download to your mobile device. But if you wish to use the search power of Calibre to locate books that meet specific criteria to download, then Calibre Server is useless. ***


2012. Calibre DRM removal plugins for Kindle, Nook, Kobo, PDF, EPUB and other ebooks



DRM (Digital rights management) is a technology for access control that is used by ebook publishers and inhibits uses of ebooks that were not desired or foreseen by the content provider. When you buy an e-book with DRM you don't really own it but just have a permission to use it in a manner dictated to you by the seller. DRM limits what you can do with e-books you have "bought". Often people who buy books with DRM are unaware of the extent of these restrictions. These restrictions prevent you from reformating the e-book to your liking, including making stylistic changes like adjusting the font sizes, although there is software that empowers you to do such things for non DRM books. People are often surprised that an e-book they have bought in a particular format cannot be converted to another format if the e-book has DRM. So if you have an Amazon Kindle and buy a EPUB book sold by Barnes and Nobles, you should know that if that e-book has DRM you will not be able to read it on your Kindle. ***


2012. Book library software Calibre gets a modern new look



The latest version of e-library organizer Calibre 0.9 features a new "modern" appearance. This update provides a more contemporary look to the interface with emphasis highlighting, gradients, rounded corners and more. The refreshed e-book viewer includes a new "paged" mode, where the text is divided into pages. This allows you to view multiple pages on the screen simultaneously. Calibre can now connect wirelessly and via USB to Android devices. Modern Android devices often use a specific "MTP" protocol when connecting through USB. Calibre now supports this protocol on Windows (Vista and later) and Linux. Another new feature is Calibre Portable, which keeps the Calibre library and settings bundled with the Calibre program. This means you can store the entire setup on a USB drive and take it with you. Calibre's conversion engine now fully supports Amazon's new KF8 format. It can convert KF8 books to other formats and convert other formats to KF8. To convert to KF8, set the output format in the Calibre conversion dialog to AZW3.


2011. Video: Calibre Tutorial about its features and interface


Kovid Goyal, the creator of the popular home library management software Calibre created this video tutorial called "How to use Calibre - a look at its features and user interface". It shows some tips of how to optimize your usage of the program user interface. The main window interface consists of four areas: the book list (shows the books in your library), library browser sidebar (allows to browse your collection by various categories like series, publishers, rating...), book detail view (shows the book cover, formats available, comments..) and the upper search bar (allows to find books in your calibre collections). The user interface areas can be risized and hidden. You can also rearrange/hide columns in the book list. Watch the video about this robust library management software.


2011. Book management program Calibre integrates with book websites



The latest version of book manager Calibre 0.8 can now search across numerous web stores like Amazon, Barnes & Noble, Waterstones and others for e-book editions of the book you want. The results are shown sorted by price, making it easy to find the most affordable edition to add to your collection. This feature, like the rest of Calibre, is plugin-based, so expect new stores to be added in the future. When downloading covers for a single book, Calibre will now retrieve covers from all available online sources and let you choose the one you prefer, rather than making the choice for you. Additionally, you can now perform search and replace operations on the book list in your Calibre library using the Bulk Metadata Edit tool and create complex file names from book metadata when exporting books from the Calibre library. The new Virtual Columns feature allows you to add custom metadata fields and automatically populate them from Calibre. For instance, you can add an ISBN column or a column to display the formats the book is available in.
