Most e-book formats can be edited, for example, by changing the font, font size, margins, and metadata, and by adding an auto-generated table of contents. Features Ĭalibre supports many file formats and reading devices. In 2008, the program, for which a graphical user interface was developed, was renamed 'calibre', displayed in all lowercase. With support from the MobileRead forums, Goyal reverse-engineered the proprietary Broad Band eBook ( BBeB) file format. An overview of the Calibre search syntax is available here.On 31 October 2006, when Sony introduced its PRS-500 e-reader, Kovid Goyal started developing libprs500, aiming mainly to enable use of the PRS-500 formats on Linux. Search supports basic searches, e.g., for single words and phrases, but also Boolean searches and phrases near others. Once books are indexed, Calibre will run full text searches across the entire library whenever the search function is used. The fast indexing speed option requires more resources, but it finishes indexing operations faster. The default indexing speed is set to slow, which is done to limit the impact on the computer when the indexer runs. Select the FT icon next to the search field in Calibre's interface and check the 'index books in this library to allow searching their full text' option when the configuration window opens. Calibre can be configured to index the text of all books in the library to make it searchable. Calibre 6.0 supports Apple Silicon CPUs on Mac OS devices and ARM CPUs on Linux.Īnother main improvement is the ability to run full text searches using Calibre's indexing functionality. The new version of the ebook software supports new CPU architectures.
