DL as collection/information system



“a collection of information that is both digitized and organized”
-- Mike Lesk, NSF
“networked collections of digital text, documents, images,
sounds, scientific data, and software”
-- PITAC report
DL as organization:

“an organization that provides the resources, including the
specialized staff, to select, 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”
-- Digital Library Federation
What is a digital library?
