   In contrast, the most succinct definition arising from the community of library practice is that set forth by the Digital Library Federation (DLF): "Digital Libraries are organization that provide the resources, including the specialized staff, to selct, structure, offer intellectual access to, interpret, distribute, preserve the integrity of, and ensure the persistence over time of collections of digital works so that they are readily and economically available for use by a defined community or set of communities".

   2003, Ann P. Bishop, Nancy A. Van House, Barbara Pfeil Buttenfield, Digital Library Use: Social Practice in Design and Evaluation, page 87

   From its beginning, the DLF has sought to "bring together—from across the nation and beyond—digitized materials that will be made accessible to students, scholars, and citzens everywhere, and that document the building and dynamics of America's heritage and cultures."
