CrossRef

CrossRef is a non-profit organization that enables cross-publisher citation linking of the scholarly literature via Digital Object Identifiers (DOIs). CrossRef member organizations can use the Cited-by Linking service that provides basic information about the scholarly literature citing a particular DOI that they have published. All other users can use the CrossRef OpenURL service which provides citation counts (the `fl_count' attribute), but no information about the citing literature. Lagotto handles both scenarios.

Required configuration fields

Cited-by

Add username and password provided by CrossRef in the Publisher Configuration tab of the CrossRef source. This setting is specific to a particular publisher associated with the user entering this information.

OpenURL

For articles without a publisher the openurl_username in the Configuration tab of the CrossRef source will be used. You can register for a CrossRef Query Services account here.
