The library relies on resource sharing, interlibrary loan and document delivery as an extension of the collection. Interlibrary loan is a formal agreement among libraries to share materials with, or provide copies to, other libraries. Because of the ever increasing publication of materials and the impossibility of one library owning everything, the importance of interlibrary loan has intensified. Collins Memorial Library enhances its borrowing and lending capabilities through membership in the OCLC (Online Computer Library Center) network, an automated system that connects the library to over 27,000 members in 171 countries as well as through its cooperative agreement with the Orbis/Cascade Alliance (Summit) consortium of 36 Oregon and Washington libraries. Document delivery service, the provision of high-resolution photocopies of journal articles more rapidly than the traditional interlibrary loan service, is another way that the library seeks to improve access to information for its users.
