SYCAMORE – The last 50 years have brought innovation, growth and other changes to DeKalb County, all of which are documented in a new book.

The DeKalb County Genealogical and Historical Society hosted a sneak peak of its new book “Acres of Change: A History of DeKalb County, Illinois 1963-2012” Thursday as part of the Sycamore History Museum’s monthly Brown Bag Lunch.

Contributing authors Marcia Wilson and Barry Schrader gave guests a glimpse into the chapters of the book at the DeKalb County Community Foundation, 475 DeKalb Ave. in Sycamore.
