Excerpts from the Preface: The Library of the Bureau of Agricultural Economics is the economics branch of the Library of the U. S. Department of Agriculture. It receives its periodicals from the Department Library and direct by mail. Periodicals from both of these sources have been included in this list, even though many are filed in the Department Library. Where possible, incomplete years in sets have been indicated but no attempt has been made to indicate missing numbers within the last two years and lacking title pages and indexes have not been indicated. No attempt has been made to indicate changes in title. Periodic reports of the Bureau of Agricultural Economics have been omitted as these reports have been listed in the Bureau's mimeographed publication entitled, Agricultural Economic Reports and Services of the Bureau of Agricultural Economics (latest edition, April 1932), issued by the Division of Economic Information.
