Turning DOIs into formatted citations

Today two new content types were added to dx.doi.org resolution for Crossref DOIs. These allow anyone to retrieve DOI bibliographic metadata as formatted bibliographic entries. To perform the formatting we’re using the citation style language processor, citeproc-js which supports a shed load of citation styles and locales. In fact, all the styles and locales found in the CSL repositories, including many common styles such as bibtex, apa, ieee, harvard, vancouver and chicago are supported.

Determining the Crossref membership status of a domain

We’ve been asked a few times if it is possible to determine whether or not a particular domain name belongs to a Crossref member. To address this we’re launching another small service that performs something like a “reverse look-up” of URLs and domain names to DOIs and Crossref member status. The service provides an API that will attempt to reverse look-up a URL to a DOI and return the membership status (member or non-member) of the root domain of the URL.

Family Names Service

In ApisFamily Names

Today I’m announcing a small web API that wraps a family name database here at Crossref R&D. The database, built from Crossref’s metadata, lists all unique family names that appear as contributors to articles, books, datasets and so on that are known to Crossref. As such the database likely accounts for the majority of family names represented in the scholarly record. The web API comes with two services: a family name detector that will pick out potential family names from chunks of text and a family name autocompletion system.
