Excerpt from The Lower Peninsula of Michigan: An Inventory of Historic Engineering and Industrial SitesThe Historic American Engineering Record (haer) is a program of the Office of Archeology and Historic Preservation, National Park Service and is responsible for documenting and thus preserving America's engineering and industrial heritage. As part of its program, haer prepares inventories or lists of significant engineering and industrial sites in all parts of the country. It was decided to inventory the Lower Peninsula of Michigan during the summers of l975-l976 and then conduct a separate inventory of the Upper Peninsula at a later time.It has been an ambitious undertaking because of the immense size of the area surveyed (sixty-eight counties in the Lower Peninsula) and the rich industrial history of the state. There were few systematic surveys on which to draw. Haer previously gathered information on only a handful of sites, while the existing county and local surveys concentrated on structures of architectural, rather than engineering or industrial, interest.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
