Census. This census captured a radically changed America, as it was still struggling to escape the turmoil of the decade-long Great Depression and the migrations and economic upheaval it caused and on the verge of getting into World War II. Genealogy & Local History Department Manager Patricia Van Skaik will introduce the 1940 census with a special program called “The 1940 Census Is Here: Techniques for Achieving Top Search Results.” This will provide strategies for finding and using the information from that census. The presentation will be held in the Genealogy & Local History program space on the third floor. Van Skaik is a recipient of the RootsTech Distinguished Speaker Award and lectures widely on the intersection of history, technology and librarianship. For more information, contact the department at 513-369-6905. 2 p.m. Cincinnati Public Library, downtown branch. 2802 Vine St., cincinnatilibrary.org.
