Monthly Catalog of U.S. Government Publications, 1895-1976
The Library now has online access to the Monthly Catalog of U.S. Government Publications, 1895-1976.
For finding U.S. federal publications, the Monthly Catalog is an invaluable complement to the Orbis library catalog (in which the cataloging of Yale's U.S. federal depository print collection is nearly complete), the MORRIS Law Library catalog, and WorldCat, not least because the Monthly Catalog indexes publications that were not distributed through the depository program.
