Historical geographic material, like maps, plans, and air photos, although collected and persevered by libraries, archives, and other heritage organizations, are often hidden from the general public. They can be difficult to find, access, and use. Fortunately, these caches of cartographic gems have been recognized and valued for their significant contribution to research. As a result, many of these collections have been recently digitized and made available to the public, directly and freely, online. Acting as a comprehensive guide to online historical, cartographic and other visual resources, Discovering and Using Historical Geographic Resources on the Web provides library and archival staff, and their users, with information on how to locate, interpret, understand, and use these resources. Even for experts, this book can serve as a handy reference that summarizes the different types of maps published, providing comprehensive lists of where to access them. This book is written for all library staff members who answer reference questions and provide library instruction, and for those who are interested in digitizing their own cartographic collections. It will also attract history buffs and scholars in environmental studies, history, earth sciences, anthropology, and more.
