'''RedLightGreen''' was a [database](/source/database) of [bibliographic](/source/bibliography) descriptions on the [Web](/source/World_Wide_Web) created by [Research Libraries Group (RLG)](/source/Research_Libraries_Group).<ref>RedLightGreen, http://www.oclc.org/research/activities/redlightgreen.html {{Webarchive|url=https://web.archive.org/web/20131014085643/http://www.oclc.org/research/activities/redlightgreen.html |date=14 October 2013 }}</ref> It used a set of four million records extracted from [OCLC](/source/OCLC)'s [WorldCat](/source/WorldCat) database, and was designed to help novice users make selections from the vast bibliographic resources they would encounter in such a large set.<ref>{{Cite web |url=http://searchenginewatch.com/article/2068054/Searching-for-Library-Books-with-RedLightGreen |title=Search Engine Watch |access-date=27 October 2013 |archive-date=29 October 2013 |archive-url=https://web.archive.org/web/20131029202243/http://searchenginewatch.com/article/2068054/Searching-for-Library-Books-with-RedLightGreen |url-status=live }}</ref> RedLightGreen also allowed users to create [citation](/source/citation)s for works found.

Work on RedLightGreen began in 2001 with funding from the [Andrew W. Mellon Foundation](/source/Andrew_W._Mellon_Foundation). It was one of the earliest experiments with the [Functional Requirements for Bibliographic Records](/source/Functional_Requirements_for_Bibliographic_Records) which provides a structured view of bibliographic data.<ref>{{Cite web |url=http://www.cni.org/pbs/cni2003springpb/redlightgreen-accelerates-research-rlgs-union-catalog-on-the-web/ |title=CNI Spring 2003: RedLightGreen |date=8 April 2003 |access-date=27 October 2013 |archive-date=29 October 2013 |archive-url=https://web.archive.org/web/20131029211027/http://www.cni.org/pbs/cni2003springpb/redlightgreen-accelerates-research-rlgs-union-catalog-on-the-web/ |url-status=live }}</ref> On 1 July 2006, RLG was merged with [OCLC](/source/OCLC), and it was announced that the RedLightGreen service would be replaced by [WorldCat](/source/WorldCat), via Open WorldCat, available at WorldCat.org.<ref>[http://www.oclc.org/news/releases/200618.htm "RLG to combine with OCLC"] {{Webarchive|url=https://web.archive.org/web/20060908225658/http://www.oclc.org/news/releases/200618.htm |date=8 September 2006 }} (Press Release, Dublin, Ohio, USA, 3 May 2006)</ref>
