The Frederick and Patricia Shroyer Science Fiction, and Fantasy Book Collection consists of late 19th Century to 20th Century genre fiction, 1890 to 1950 and thirty-one periodical titles from 1897 to 1909. Dr. Fredrick Shroyer was a professor at California State University, Los Angeles who donated his collection in 1981. He collected all significant authors from 1890 to 1950 in both genres. A separate gift at a later date was 360 short stories from the 1920s and 1930s in the form of tearsheets in indexed pressboard covers together with runs of thirty-one periodicals from 1897 to 1909. Many of the books have their original dust jackets.
