The Mary Brubaker papers date from 1999 and measure 0.5 linear inches. They consist of a profile and postcard photograph of Mary Brubaker, original and edited copies of Brubaker's chapter, "The Women Who Helped to Keep the Peace," from the book Behind the Badge: Stories and Pictures from the DMPD, and a newspaper clipping which discusses that book. A copy of the book is shelved with printed works at the Iowa Women's Archives.
