System/360 (Early Publications: 1964 - )

These PDF documents, starting from 1964, are those parts of the OS/360 “System Reference Library” (SRL) with enduring relevance and are also the earliest System/360 publications available on the web. Given IBM’s stubborn insistance on full upward compatibility, all facilities described here (most of which are still supported) continue to function as described, even on the most recent z/Architecture systems. Where applicable, these publications often present the essence of the topic while being much shorter and easier to digest.
