"An academic library is defined in terms of its collection and the
services provided to make information available to the user community...
Collection development is practiced through implementation of theories devised
in library science and related disciplines...
"Collection Development is responsible for acquiring materials that have
been selected for library collections and for purchasing library materials
in all formats: books, periodicals, electronic resources, serials, music scores,
sound recordings, videos, manuscripts, and microforms."
