Researchers from CRL member libraries have access to the collections through interlibrary loan, digitized collections or by appointment in the CRL reading room. Through CRL's Digitize on Demand service, CRL member libraries may request digitization of most individual titles, volumes, or microform reels. Requests take approximately ten working days to complete.
