In addition to the music itself, the AMRC's collections document the study and criticism of music.  The Center holds writings, oral histories, research materials, and other materials documenting an eclectic collection of music scholars from around the country.

Wesley V. Blomster papers

The Wesley V. Blomster papers comprise personal and professional materials encompassing his dual career as music critic and German language professor from 1955 to 2012. A majority of materials in this collection are arranged chronologically by year and include a wide assortment of Blomster's original newspaper article clips and memorabilia from his travels and concert- going, intermingled with letters of correspondence, binders of Daily Camera photocopies, and volumes of typewritten Daily Camera drafts; program note folders arranged alphabetically
by composer's last name within genre-specific binders; and boxes of VHS review copies of operas and historical programs. The pre-arranged organization of materials reveals Blomster's deliberate attempts to maintain a specific presentation of his materials. Some materials, such
as personal diary entries, were originally interspersed in collections of typewritten Daily Camera drafts. These and other carefully-selected materials from the collection have been restricted due to their extremely personal nature. Some items, mostly book reviews, are at times outside of the chronological order for the series. The arrangement order of materials follows Blomster's pre- arranged organization.
