Irma M. Walker (1885 - 19xx) was an American librarian. Born in Wisconsin, Walker graduated from Beloit College in Beloit, Wisconsin, and the library program at the University of Wisconsin Madison. Walker worked as a teacher before she got her first job as a reference librarian in Long Beach, California. Then she became the reference librarian in Hibbing, Minnesota, a position she held from at least 1920 until she resigned in August 1937. Walker was the researcher who compiled the information for the 1929 pictorial map of the Arrowhead region of Minnesota published by the American Association of University Women. In 1930 she was living with Dorothy Hurlbert, another librarian at the Hibbing Public Library. By 1940 she was working as a librarian in Grand Forks, North Dakota.
