1. Chronological
The Music Library collects materials (books, music, and recordings) related to western music from antiquity to the present, American popular music from the origins of recorded sound to the present, and studies and recordings in the field of ethnomusicology dating back to the birth of the field in the early 20th century.
2. Formats
Material is purchased for the library regardless of format (currently, this includes books, scores, journals, microformats, and electronic databases and streaming media). The primary formats collected by the Media Center are CDs and streamed audio and video; LP recordings are purchased if a desired title is available only in this format. DVD is the preferred format for video recordings. The library will acquire a desired title on Blu-ray if it is not available on DVD or if needed for teaching/research purposes. Specialized formats such as data sets, corpora, and manuscripts are purchased on an ad hoc basis to meet research needs or to support growing fields of interest.
3. Geographical
Emphasis on United States and western European imprints (due primarily to availability), as well as regions studied in the ethnomusicology program (ex: Africa, Caribbean, South Asia). The collection is particularly strong in the music of Philadelphia, and in works about Philadelphia music and musicians.
4. Language
No limitations, although emphasis is on English, western European languages, and regional areas under study in ethnomusicology.
5. Publication Dates
Chiefly, purchases are limited to current material; retrospective collecting is considered on a case-by-case basis.
6. Open Access
Products that lead to open access publications and resources receive priority. Proprietary resources in which we would not normally invest receive greater consideration if they support a competitive market with freely accessible resources.
