(excerpted from FRASER™website:
The Federal Reserve Archival System for Economic Research is the newest project by the Research Division of the Federal Reserve Bank of St. Louis to expand on its mission to provide economic information and data to researchers interested in the U.S. economy. On this web site you will find links to scanned images (in Adobe® Acrobat® PDF format) of historical economic statistical publications, releases, and documents.
When used in connection with data contained in FRED® (Federal Reserve Economic Data), FRASER™ allows the researcher to create uninterrupted data series by accessing sources previously available only in printed form and those currently available electronically (on FRED®). In addition, the ability to retrieve series presented in preliminary, revised, and final releases provides a powerful tool in recreating and evaluating previous economic research and policy.
