Historic Map Works Library Edition is one of the most extensive digital map collections available, with over 200,000 high-resolution, full color historic maps.

The core of the collection consists of property and land ownership maps illustrating the geographic and development history of the United States. This unique content allows genealogists, historians, and researchers to track the "residential genealogy" of families and locations.

Historic Map Works collections include:

• Property Maps, over 100,000 maps covering the development of the United States since the late 1700's to the present
• Antique Maps, over 100,000 antiquarian maps covering the world from the 15th to 19th centuries, drawn from the University of Southern Maine's Osher Map Library
• City Directories & Illustrations, thousands of related listings, images, business ads, and statistics

The special attention to image quality allows users to see incredible detail that supports research into ancestral lands, land boundaries and structures, geographic names and locations, community growth, topography, and more.

Plus, with collections that span decades and centuries, researchers can easily examine change over time-from big cities to small rural areas around the world.

The straightforward interface lets users search Historic Maps Works by keywords, location names, and other advanced features. They can also easily browse the collections using an intuitive point-and-click world map. Other features such as image previews, zoom in/out, and image cropping make reviewing and using the maps easy.

Historic Maps Works Library Edition is an exclusive distribution and development partnership between ProQuest and Historic Map Works, which brings the collection to libraries globally.
