The content of the scrapbooks reflects Miss Costabel's life circumstances. The bulk of the earliest programs and clippings pertain to events in San Jose where the College of the Pacific was located when Miss Costabel was a student there. The lion's share of those programs dating between 1924 and 1932 pertain to events in Stockton, where the College of the Pacific was located when Costabel was a faculty member there. She collected a small group of programs during the academic year 1927-1928, when she was a student in France. Most programs and clippings dating from 1933 onward pertain to events at San Jose, Stanford or San Francisco.

This collection consists of two scrapbooks of programs and clippings pertaining to musical and theatrical performances in northern California, New York, England and France between 1916 and 1945. The bulk of these materials concern performances in Stockton, San Jose and San Francisco, California.

Collection is open for research.
