This site, at http://govinfo.library.unt.edu/ is worth checking when looking for publications from defunct govt. agencies. I looked for OTA, for example, and found a great many publications in full text, dating as far back as to 1972. Excerpt from the site: "The University of North Texas Libraries and the U.S. Government Printing Office, as part of the Federal Depository Library Program, created a partnership to provide permanent public access to the Web sites and publications of defunct U.S. government agencies and commissions. This collection was named the "CyberCemetery" by early users of the site."
