Back for its fourth year, the St. Louis Small Press Expo once again returns to the central branch of St. Louis Public Library (1301 Olive Street; www.stlouissmallpressexpo.com) from 10 a.m. to 5 p.m. Saturday, October 14. More than 80 vendors selling comics, art, literary magazines and traditional books are scheduled to attend, providing an in-depth look at the small-press scene. A host of informative seminars and classes will also be on offer — everything from a creative writing workshop for kids to a seminar on copyrights. The library's Creative Experience area also gets in the act, with a digital drawing demo by Marie Enger and an intro-to-podcasting session. Admission to all of this is free, but bring your funds for that vendor room.
