International Interlibrary Loan reviewed current ILL practices, both domestic and international, and the importance of international ILL to achieving the mission of research libraries. Finally, the task force conducted a survey of international relationships of the ARL membership, which garnered 85 responses. These data portray a rich and complex environment within which ARL libraries operate. Based on their research and analysis, each of the three working groups produced a white paper, which informed this report. The three white papers follow in this issue of Research Library Issues. Findings 1. Research libraries provide access to information through multiple channels, including acquisition of copyrighted works, licensing agreements, ILL, purchase on demand, and more. These services entail significant expenditures in support of research, teaching, and learning. 2. Participation in ILL arrangements is a well-established practice in libraries in many countries. The Berne Convention and other international copy- right agreements do not specify any standards for ILL thus nations have considerable discretion about the terms of allowable reproduction and distribution. 3. By engaging with international partners, research libraries build relationships with libraries and institutions in other countries, develop reciprocity, and supply the materials required. These activities support and promote scholarship. 4. The proper scope and function of ILL are embedded in well-established practices that have been openly integrated into professional standards and have been widely known to and acknowledged by authors, publishers, and others for years. 5. US copyright law supports the ability of domestic libraries to participate in ILL arrangements and to send copies of some copyrighted works to foreign libraries provided the libraries meet the requirements of the law. 6. Since the 1990s, publishers and libraries increasingly use license agreements to establish use permissions that previously had been guided by US copyright law. This shift away from copyright law to contract law has affected some aspects of resource sharing. 7.
