Monographs, monographic series, serials, reference works, conference proceedings, media (including software or visual items) and recordings are regularly sought; excluded are most anthologies, dissertations, manuscripts, maps, and most collections of previously published materials.
To broaden accessibility and assist scholarship, journals are sought online (when this format is avilable). Print may be cancelled to reduce costs when ownership of the online version is assured. Online access that required additional costs with a print subscription will be sought selectively within the amount budgeted for journals. Monographs and other types are generally purchased as printed text. Other formats are considered, including digital files (online or CD), audio cassette tapes, and video tapes.
