WorldCat database reaches 2 billion holdings

“WorldCat is a database of bibliographic information created and continuously updated by some 25,000 OCLC member libraries around the world. WorldCat records describe specific works and contain a listing of institutions that own an item, referred to as “holdings.” Institutions use holdings information to create local catalogs, arrange interlibrary loans and conduct reference work.”

“WorldCat was created in 1971 so that libraries could share cataloging information from a central database, increasing workflow efficiency and the ability to locate and loan materials. It took the OCLC cooperative almost 34 years, from August 26, 1971 to August 11, 2005, to add 1 billion holdings in WorldCat. It has taken just seven years and eight months to add the next billion.” 

“WorldCat spans six millennia of recorded knowledge, from about 4800 B.C. to the present. It encompasses records for books, serials, sound recordings, musical scores, maps, visual materials, mixed materials and computer files.”

From OCLC Member Update []

“Find more about WorldCat on the OCLC website, and watch WorldCat grow as libraries around the world contribute to the database.”

(Holdings constitute a higher number than titles.  A(nother) holding is counted for each library that owns a title.

Public Library of Science (PLoS) launches a blog

"PLoS ONE launches community blog for journal authors and readers – 30 Mar 2009

PLoS ONE, a free online journal published by open access publisher Public Library of Science (PLoS), US, has announced the launch of everyONE (, a new community blog for PLoS ONE authors and readers.

As of March 2009, PLoS ONE has published over 5,000 articles, representing the work of over 30,000 authors and co-authors, and receives over 160,000 unique visitors per month. The blog is for authors who have published with the journal as well as for those who haven’t.

The blog has been named everyONE for three main reasons: PLoS ONE is for every rigorous research article that passes the publisher’s our peer-review process; it is a forum for research in every scientific discipline; and it is a source of information for every inquisitive reader with an interest in high-quality scientific research.

PLoS ONE is a peer-reviewed, open-access journal for all science and medicine. It features reports of original research from all disciplines within science and medicine. By not excluding papers on the basis of subject area, PLoS ONE seeks to facilitate the discovery of the connections between papers, whether within or between disciplines."
