&amp;#039;&amp;#039;&amp;#039;WorldCat&amp;#039;&amp;#039;&amp;#039; is a [[union catalog]] that lists the collections of 17,900 [[library|libraries]] in 123 countries and territories&amp;lt;ref name=&amp;quot;statistics&amp;quot;&amp;gt;{{cite web|url=https://www.oclc.org/en/about.html |title=About OCLC|publisher=[[Online Computer Library Center]]|accessdate=August 18, 2019}}&amp;lt;/ref&amp;gt; that participate in the [[Online Computer Library Center]] (OCLC) global cooperative.

It is the world&amp;#039;s largest [[bibliographic database]]. OCLC makes WorldCat itself available for free to libraries, but the catalog is also used for other subscription OCLC services (such as [[interlibrary loan|resource sharing]] and collection management). WorldCat is used by the general public and by librarians for cataloging and research.&lt;br /&gt;

Kilgour, a distinguished librarian who nearly 40 years ago transformed a consortium of Ohio libraries into what is now the largest library cooperative in the world, making the catalogs of thousands of libraries around the globe instantly accessible to far-flung patrons, died on Monday in Chapel Hill, N.C.

In 2003, OCLC began the &amp;quot;Open WorldCat&amp;quot; pilot program, making shorter records from a some of WorldCat available to partner web sites and booksellers. OCLC did this so that subscribing member libraries&amp;#039; collections would become more accessible.&amp;lt;ref&amp;gt;{{Cite journal|last=O&amp;#039;Neill|first=Nancy|date=Nov–Dec 2004|title=Open WorldCat Pilot: A User&amp;#039;s Perspective|journal=Searcher|language=English|volume=12|issue=10|pages=54–60|oclc=201889986|issn=1070-4795}}&amp;lt;/ref&amp;gt;&amp;lt;ref&amp;gt;{{cite web |last=Quint |first=Barbara |date=October 27, 2003 |title=OCLC project opens WorldCat records to Google |url=http://newsbreaks.infotoday.com/NewsBreaks/OCLC-Project-Opens-WorldCat-Records-to-Google-16592.asp |website=infotoday.com |publisher=[[Information Today]] |accessdate=2019-06-26}}&amp;lt;/ref&amp;gt;&lt;br /&gt;

In October 2005, the OCLC technical staff began a [[wiki]] project called WikiD. It let readers add comments and structured-field information to any WorldCat record.&amp;lt;ref&amp;gt;{{Cite web|url=http://www.oclc.org/research/activities/wikid.html|title=WikiD|publisher=OCLC|language=en-US|accessdate=March 5, 2015}}&amp;lt;/ref&amp;gt; WikiD was later phased out, although WorldCat later incorporated [[user-generated content]] in other ways.&amp;lt;ref&amp;gt;{{Cite journal|url=http://www.oclc.org/content/dam/oclc/publications/newsletters/nextspace/nextspace_007.pdf|title=A WorldCat community: using WorldCat.org to build a social network of the world&amp;#039;s library users|last=Storey|first=Tom|date=September 2007|journal=NextSpace|accessdate=2019-06-26|publisher=OCLC|issue=7|pages=16–17|issn=1559-0011|quote=Online ratings, tags, reviews, recommendations, lists, rankings, personal profiles—the social media revolution is here.
