The Wall Street Journal reviews two exhibits from Chicago’s Festival of Maps: the flagship Field Museum exhibit (of course), along with one of two exhibits at the Newberry Library, Ptolemy’s Geography and Renaissance Mapmakers. (Actually, the Newberry claims three exhibits, since Newberry historians curated the Field Museum exhibit.) The remaining Newberry exhibit is Mapping Manifest Destiny: Chicago and the American West; Doug Knox writes to report that a full-colour catalogue of the exhibit is available from the library’s bookstore.
