The Maine Shared Collections Cooperative (MSCC) is a collaborative of 40 plus academic and public libraries in the state of Maine who have collectively agreed to retain more than 1.5 million print books for a minimum of 15 years. Participating libraries agree to make retained materials accessible to library users across Maine and beyond, allowing other libraries to consider withdrawing their own local copies safe in the knowledge that the content is being protected for future use. The founding of MSCC was funded in part by the Institute of Museum and Library Services (IMLS).
