Client for the Open Citations Corpus http://opencitations.net/ (OCC)

OCC created their own identifiers called Open Citation Identifiers (oci), e.g.,

020010009033611182421271436182433010601-02001030701361924302723102137251614233701000005090307

You are probably not going to be using oci identifiers, but rather DOIs and/or PMIDs and/or PMCIDs. See ?oc_lookup for methods for cross-walking among identifier types.

If you'd like to use the OpenCitations Sparql endpoint yourself you can find that at http://opencitations.net/sparql

You can pass in more than one identifer to each of the above functions:
