Center for Research Libraries


Center for Research Libraries (CRL)



The Center is a consortium of nearly 200 North American academic and research libraries that collectively acquires, preserves and provides access to primary resources for research and teaching in the humanities, sciences, and social sciences. Its collections consist of more than four million publications, which are made available to member institutions through interlibrary loan and electronic delivery.


By becoming the first overseas member of the CRL's Global Membership program, HKU Libraries' holdings are greatly enhanced through access to a much wider range of otherwise inaccessible research materials that are normally beyond our fiscal means.


The contents of its collections are primarily outside the core of high demand titles commonly collected and retained by North American libraries. Overall the emphases are on contents produced outside the US, with the exception of the publications of the US government.
