The mission of the Online Computer Library Center (OCLC) Research is to expand knowledge that advances OCLC's public purposes of furthering access to the world's information and reducing library costs. OCLC Research is dedicated to three roles: (1)To act as a community resource for shared research and development (R&D); (2) To provide advanced development and technical support within OCLC itself; and (3) To enhance OCLC's engagement with members and to mobilize the community around shared concerns. This report pulls together recent work in those three areas, providing highlights of OCLC Research activities, focusing on 2012 and the first months of 2013. It provides a flavor of important themes in the internal work and the external shared work agenda. Outputs include prototype systems or services, published reports, webinars, podcasts, videos and meetings ranging from task group sessions to our influential symposium, "Libraries Rebound." OCLC feel that this report presents a story of achievement and contribution, representing significant value provided to OCLC, the membership, and the larger community. Contents include: (1) Shared community R&D--the OCLC Research work agenda; (2) Advanced development and consultation within the OCLC enterprise; (3) Member and Partner engagement; and (4) OCLC Research staff.
