Calibre 9.9 has been released as the latest update to the popular open-source e-book manager, bringing several usability improvements, bug fixes, and refreshed news source support.
The release adds a new option allowing users to keep the current search active when switching between Virtual libraries. The setting is under Preferences > Searching and is useful for users who organize large book collections across multiple library views but want their active search context to remain unchanged while moving between them.
Another notable improvement lands in the Pages column, which now supports accurate page counting for fixed-layout EPUB files. Calibre 9.9 also improves the “Add from ISBN” feature by ignoring spaces around the colon used to separate an identifier type from its value. In addition, the “Get books” feature receives an updated and improved WolneLektury store integration.
On top of that, the e-book viewer now correctly handles search match offsets in normal search mode when the text contains non-BMP Unicode characters. These characters sit outside the Basic Multilingual Plane and include many emoji, historic scripts, and less common symbols that could previously affect search positioning inside the viewer.
The content server has been adjusted as well to apply null metadata when serving book files, matching the behavior when saving books to disk. For Linux users, Calibre 9.9 fixes SSL certificate loading on Fedora 44, addressing a platform-specific issue that could affect secure network operations.
Other fixes include a correction in the bulk metadata dialog, where the Backspace key did not work in number input boxes when the value was set to Undefined.
Finally, the release expands Calibre’s built-in news fetching support with new Hungarian and Czech news sources contributed by bubak, along with SuperInteressante by Pedro Henrique Souza.
Existing news sources have also been improved, including Indian Express, Business Standard, BBC, New Criterion, Associated Press, ProPublica, LA Times, Washington Post, New Yorker, TLS Magazine, Asian Review of Books, Vox, The Conversation, Chicago Tribune, New Republic Magazine, and TIME Magazine.
