Dorothy Hurlbert (1884 - 19xx) was an American librarian. Born in Illinois, Hurlbert worked as the librarian of the Hibbing (Minnesota) public library from 1915 until 1933. She was part of the research committee that created the 1929 pictorial map of the Arrowhead region of Minnesota. Hurlbert is credited with creating what might be the United States' first bookmobile. In 1919, she loaded 1,200 books on a 2-ton, 35-horsepower truck chassis and served the book hungry community of Iron Range miners and loggers, traveling over 160 square miles. She delivered over 50,000 volumes that first year, and within the next decade Hurlbert had developed relationships with sixteen mining locations, ten rural communities, and eleven schools. Apparently, in 1928, Hurlbert resigned as librarian, but was quickly reinstated, an affair the Minneapolis Star referred to as a 'heated controversy' which swirled around unsubstantiated allegations that Hurlbert was 'uncooperative'. Per the 1930 census, Hurlbert was living with a partner Irma Walker (who also happened to be the chief researcher of the Arrowhead pictorial map).
