Citation types supported by Manubot.

Manubot allows users to cite different types of persistent identifiers. Metadata source indicates the primary resource used to retrieve bibliographic metadata. For certain identifier types, additional metadata sources are queried should the primary fail. For example, when translation-server ISBN lookup fails, Manubot tries Wikipedia’s Citoid (https://www.mediawiki.org/wiki/Citoid) service followed by the isbnlib (https://github.com/xlcnd/isbnlib) Python package. When translation-server URL lookup fails, Manubot then tries Greycite (http://greycite.knowledgeblog.org/) [15]. Raw citations enable citing works when no supported persistent identifiers exist, but require that the user specifies the metadata. Finally, authors may optionally map a named tag to any of the supported identifier types. In this example, the tag avasthi-preprints represents the DOI identifier 10.7554/eLife.38532.
