The International WOCE bibliography was started in October 1994 to provide a convenient reference source for WOCE Investigators as well as a record of the achievements of the project. It is a collaborative project between the WOCE IPO, the WOCE Data Information Unit (at the University of Delaware) and the UK National Oceanographic Library at the Southampton Oceanography Centre. As of 31 Dec 2004 the bibliography contained 8240 articles, of which 2100 published papers and 1430 unpublished papers are directly attributable to WOCE.
