Some folders of research materials are organized alphabetically primarily by the location and culture they pertain to, and others by a single art or material or other subject, often with several locations represented. Originally, these were all interfiled in one alphabetical series, but they have been split into seperate series for clarity: Series 2: Arts by Location, Series 3: Arts by Subject, and Series 4: Collection Management. Series 1: Writings is also alphabetical. Series 5: Cataloging, Subseries 1: Helen Louise Allen Textile Collection is chronological. Series 5: Cataloging, Subseries 2: Ruth Ketterer Harris Library is in its original order.
