The collection of the P.E.O. Sisterhood, BE Chapter dates from 1933-1994 with most of the collection covering 1933-1990. The collection contains: early correspondence that documents the formation of the chapter, scrapbooks documenting the activities of the organization, president's letters describing annual activities and a video explaining the founding of the P.E.O. Sisterhood in Mount Pleasant, Iowa.

The correspondence from the formative years documents the dialogue between chapter founder Grace Northrop and the state organization. This correspondence shows the reasons for the chapter's founding and the personalities of the state and chapter presidents.

The president's letters document the annual activities of the organization. They cover 1938-1992 and summarize the year's activities in the president's own words.

The scrapbooks contain a variety of materials, some of which have been separated into folders. The scrapbooks are in chronological order by presidents. Organizational documents such as by-laws and informational documents such as annual meeting programs are included. The newspaper clippings pertain to chapter members and their families. The photographs are of chapter activities such as initiations and annual events, like the Christmas House.

The videotape was made in 1994 and documents a 1991 trip made by two BE chapter members to Mount Pleasant, Iowa. During the trip the members interviewed the original chapter A curator. They gathered information from her and used it to describe the foundation of the organization. The tape consists of still color slides narrated by a BE chapter member, with piano music played by another chapter member. Tape-recorded segments of Enola Carter, chapter A curator are included. A script of the tape, which is a good guide, but is not verbatim, is also included. The tape is 32 minutes long.
