Current Exhibition:

Women in Cartography Exhibit

OML is pleased to present Women in Cartography. This exhibition recognizes and celebrates the long overlooked role of women in the world of mapping; bringing their stories, accomplishments, and most importantly their maps to light.

Curated by Alice Hudson, former Chief of the Map Division at the New York Public Library, Women in Cartography showcases the works of better-known women cartographers such as Marie Tharp, who, in partnership with Bruce Heezen, created the first scientific map of the entire ocean floor, and, Agnes Sinclair Holbrook who created the Hull-House maps, statistical cartographic presentations of social data from the immigrant rich Near West Side neighborhoods of Chicago.

Women in Cartography will run from March 26, 2015 to October 9, 2015. Like all Osher Map Library exhibitions, there is no charge for admission and free parking is available in the USM parking garage.

Hours are: 10am to 4pm on Tuesdays and Wednesdays; 10am to 8pm on Thursdays; and 10am to 2pm on Saturdays. Please note that we are not open holiday weekends. To verify open hours, please check OML's online calendar or call us at 207-780-4850.
