The fourth annual Sacramento Archives Crawl showcases items from 23 libraries, archives and special collections, which will be on display at four locations, the California State Archives, the California State Library, the Center for Sacramento History and the Sacramento Public Library. The free event is from 10 a.m. to 4 p.m. Saturday. Collect a stamp from at least three of the locations and get a set of commemorative coasters. Among the highlights is a screening of digitized rare films and home movies at the Tsakopoulos Library Galleria. For information, go to www.sacarchivescrawl.blogspot.com.
