OCLC is introducing the Expert Community Experiment, which enables
cataloging members to make more changes to WorldCat records. During the
Experiment, members with full-level cataloging authorizations have the
ability to improve and upgrade WorldCat master records. The Experiment
begins in February 2009 and lasts six months.

OCLC is offering several introductory web information sessions in
February. Please see the Expert Community Experiment information webpage
for more information, and to register for one of the sessions:
