What are Primary and Secondary Sources?

  • Primary source materials are first-hand, unfiltered items that document history, often created around the time an event occurred. These items can include letters, documents, memoirs, diaries, newspapers, ledgers, photographs, videos, and artifacts.


  • Secondary sources are interpretations, descriptions, and analyses of evidence provided by primary sources.  Secondary sources are published as books (sometimes called monographs), chapters in books, scholarly journal articles and dissertations.

From the Collections

Swingmasters Band 1944

The Swingmasters were a regular feature and popular student group at Schreiner Institute in the 1940s. The 1943 Recall yearbook says the Swingmasters; "played for all Schreiner dances, held at intervals of approximately two weeks throughout the year, and had a number of dates for off-campus groups. Although hampered by continuous changes in the personnel of the group because of the calls of armed services, these lovers of swing music were always able to produce a good program, and contributed much toward the entertainment of the student body."
