and sold it in 2010 to EBSCO Industries. OCLC owns 100% of the shares of OCLC PICA, a library automation systems and services company which has its headquarters in Leiden in the Netherlands and which was renamed "OCLC" at the end of 2007. In July 2006, the Research Libraries Group (RLG) merged with OCLC. On January 11, 2008, OCLC announced that it had purchased EZproxy. It has also acquired OAIster. The process started in January 2009 and from October 31, 2009, OAIster records are freely available via WorldCat.org. In 2013, OCLC acquired the Dutch library automation company HKA and its integrated library system Wise, which OCLC calls a "community engagement system" that "combines the power of customer relationship management, marketing, and analytics with ILS functions". OCLC began offering Wise to libraries in the United States in 2019. In January 2015, OCLC acquired Sustainable Collection Services (SCS). SCS offered consulting services based on analyzing library print collection data to help libraries manage and share materials. In 2017, OCLC acquired Relais International, a library interlibrary loan service provider based in Ottawa, Canada. A more complete list of mergers and acquisitions is available on the OCLC website. Criticism In May 2008, OCLC was criticized by Jeffrey Beall for monopolistic practices, among other faults. Library blogger Rick Mason responded that although he thought Beall had some "valid criticisms" of OCLC, he demurred from some of Beall's statements and warned readers to "beware the hyperbole and the personal nature of his criticism, for they strongly overshadow that which is worth stating". In November 2008, the Board of Directors of OCLC unilaterally issued a new Policy for Use and Transfer of WorldCat Records that would have required member libraries to include an OCLC policy note on their bibliographic records; the policy caused an uproar among librarian bloggers. Among those who protested the policy was the non-librarian activist Aaron Swartz, who believed the policy would threaten projects such as the Open Library, Zotero, and Wikipedia, and who started a petition to "Stop the OCLC powergrab". Swartz's petition garnered 858 signatures, but the details of his proposed actions went largely unheeded. Within a few months, the library community had forced OCLC to retract its policy and to create a Review Board to consult with member libraries more transparently. In August 2012, OCLC recommended that member libraries adopt the Open Data Commons Attribution (ODC-BY) license when sharing library catalog
