CrossRef is an association of scholarly publishers that develops shared infrastructure to support more effective scholarly communications. CrossRef’s general purpose is to promote the development and cooperative use of new and innovative technologies to speed and facilitate scholarly research. CrossRef’s specific mandate is to be the citation linking backbone for all scholarly information in electronic form

A prototype of a new linking system using the Digital Object Identifier (DOI) was demonstrated at the Frankfurt Book Fair in 1999. Subsequently, several publishers including APA came together to form the Publishers International Linking Association (PILA) to operate CrossRef at the beginning of 2000.

Through CrossRef, members deposit DOIs for each journal article. Membership of Crossref allows connecting of published articles to thousands of depositories and over 15,000 global members’ network from 118 countries. Crossref receives millions of visitors every month from all parts of the world. For more information on this collaborative linking system, visit the CrossRef web site and APA organization.
