Our current Featured Exhibition is at the Osher Map Library, Masterpieces at USM: Celebrating Five Centuries of Rare Maps and Globes.

This exhibition features pieces of cartographic history from around the world, ranging from the first modern printed map in 1475 to examples of woodcut, copperplate, and lithographic map printing from the 15th through the 19th centuries.

You can explore the various exhibit sections online, from "Projecting the World" to the "Mapping of Maine." You can also get a guided tour experience by watching the Curator Tour video, where you will learn more about the history and significance of these beautiful exhibit items.


Many, but not all, of the above resources can be found through the UNH library catalog or these specialized databases.
