Call it the worst-kept secret or the best-kept secret - depending on your point of view - but the American Geographical Society Library at UW-Milwaukee's Golda Meir Library is one of the best geography resources in the country. The collection holds more than a million items, ranging from maps and atlases to pamphlets and journals, globes and photographs of all kinds. Though it is housed in Milwaukee, the AGS collection has roots in New York and covers the entire planet.
