Strongly influenced by the Functional Requirements for Bibliographic Records (FRBR), RedLightGreen organizes search results in ways that group multiple editions of the same work together, providing a very different way for users to navigate. OCLC’s Open WorldCat and WorldCat.org interfaces have some similarities to RedLightGreen, as OCLC also utilized FRBR organizational concepts in their development and will continue to explore ways to make these public interfaces to WorldCat more comfortable for users of other Web-based search interfaces.
