The University of California has worked diligently to create themed collections for teachers and others interested in California history. The Calisphere gateway provides access to 200,000 digitized items, so it's great to see that those involved have created these smaller and more manageable collections as part of this fantastic effort. The collections are organized chronologically into sections that include "1780-1880: California in Transition" and "1929-1939: The Great Depression." Each of these areas contains more detailed topical explorations, complete with Questions to Consider, a collection of images, a historical overview, and lesson plans. Educators will find these materials invaluable and anyone else interested in California history will enjoy them as well.
