Metadata

Books can use built-in online metadata providers such as GoogleBooks, ComicVine, and OpenLibrary, as well as embedded metadata from supported files.

For media in audio formats, the metadata is read from the embedded tags of the audio files. FLAC files with WebP embedded images or ID3 tags might fail to play on some browsers. Enable the Always remux flac option in the settings if you are experiencing this problem.

For books in epub format, embedded metadata can be provided. For other formats, metadata can still be provided in an external content.opf, metadata.opf or ComicInfo.xml file when needed. The ComicInfo (from ComicRack) and ComicBookInfo (from ComicBookLover) formats are supported for ComicInfo.xml files.

Additionally, information about year and issue number can be provided in the file names, as seen in the example above. For comics or magazines with issues across multiple years, the year of the first issue should be used.

The files above can contain info about what images to use for cover images. Alternatively, They can be provided as external image files named in a specific manner, as listed below.
