Although the National League of American Pen Women, Waterloo-Cedar Rapids Branch originated in 1932, their records in the Iowa Women's Archives date from 1944-2000. The records measure 12 linear inches and are divided into four series: Administrative, Secretary Books, Member Files, and Scrapbooks.

The Administrative records include annual yearbooks which list club members and outline the locations and speakers for the group's meetings.

The Member files contain information about individual members, including biographical articles, news clippings, and Jane Primus' undated book of poetry, Through the Window.

The club's scrapbooks and secretary's books, which contain news clippings, photographs, and programs of club activities, complete the collection. Where noted, some items have been disbound for preservation and placed into folders in their original order.
