A trip to ‘Oz’ in downtown Library’s Rare Book Room The Buffalo and Erie County Public Library has launched its latest exhibit in the Rare Book Room and Ring of Knowledge. The Wonderful Wizardy of Baum features 14 first editions of the L. Frank Baum collection, including The Wizard of Oz. WBFO’s Eileen Buckley had a chance to be one of the first members of the media to review the exhibit and learn about a local connection to one of his earlier books. The library has the entire canon of Baum’s works on display. It had a few of the books, then worked to acquire the rest. The first edition of the Wonderful Wizard of Oz — created in 1900 — was already in the local collection, originally purchased by the downtown library. The exhibit includes plenty of the pop culture surrounding the 1939 movie, which will mark its 75th anniversary next year.
