Papers by Guy Steele and Gerald Sussman published as AI Memos by the MIT Artificial Intelligence Laboratory between December 1975 and March 1979.
As noted in Early standards, the tone of these papers is relatively informal and their typesetting targetted 1970s computer printing technology. Scans of original printed copies are available in the digital repository of MIT research and are listed in the Computer History Museum Software Preservation Group's Scheme Project
