The Alabama Department of Archives and History is opening a major new exhibit in Montgomery. A ribbon cutting is being held Saturday on the lawn of the Archives building for a new centerpiece exhibition called "Alabama Voices." Gov. Robert Bentley and first lady Dianne Bentley will attend. The department says the exhibit is the result of a decade of research, planning and fundraising. It covers the sweep of Alabama history from the early 1700s until today. The exhibition includes more than 800 artifacts and hundreds of images. It includes sections on the state's antebellum cotton economy, the rise of industrialization, the civil rights movement and more. State schools are getting new classroom materials to go along with the exhibit.
