Should you happen to spot—say, in a yard sale, thrift store or grandparent’s house—an old copy of that classic of ornithological literature, A Field Guide to the Birds, have a close look. The first printing of the first edition of 1934 is calling for prices well over $10,000 in the antiquarian book trade. One was recently spied by keen-eyed staff in an office at the Smithsonian’s National Zoological Park. This volume has been transferred to a more suitable habitat, the Joseph F. Cullman 3rd Library of Natural History, for cataloging, preservation, research access, and education. Curator Leslie Overstreet has gathered from branch libraries three others of this title to include in the rare book library’s holdings.
