OCLC FirstSearch / WorldCat Discovery Services Illinois State Library


WorldCat Discovery refers to OCLC’s enhanced search interface, which provides access via a single portal, to WorldCat, FirstSearch databases and a central index of 2,100+ e-content collections. This new interface, featuring user defined custom display options, enables access over 1.8 billion, electronic, digital and physical resources with descriptive catalog records in WorldCat.

To ease the interface transition for OCLC users, the familiar FirstSearch platform will continue to be available along with the new WorldCat Discovery platform until the end of the year. Effective December 31st, users will no longer have access to the OCLC FirstSearch interface, marking the completed transition to the single WorldCat Discovery portal.

Keep in mind that although FirstSearch database content will be embedded into the WorldCat Discovery portal, ILLINET member libraries will retain access to all 13 databases of the former FirstSearch "base package," including Electronic Books, ArchiveGrid, ArticleFirst, CAMIO Catalog of Art Museum Images Online, OCLC FirstSearch Electronic Collections Online Abstract & Index, OAIster, PapersFirst, ProceedingsFirst, WorldCat Dissertations and Theses, ERIC, GPO Monthly Catalog and MEDLINE. These databases can be selected and searched individually.

Migration to WorldCat Discovery

ILLINET OCLC Group Services Members

Each Illinet Group Services member library will need to request a unique URL, as part of WorldCat Discovery migration.

ILLINET FirstSearch Only Members

Illinet libraries that do not use OCLC for cataloging or interlibrary loan, but only use OCLC to access FirstSearch, can continue to use the familiar FirstSearch interface until late 2016. These FirstSearch-only libraries can also use the Illinois WorldCat Discovery interface to access WorldCat, FirstSearch databases and a large central index of e-content collections in a single search.
