Sometimes understanding the history behind a technology and a community can make it easier to understand. A few months ago I wanted to better understand the history of the various reports on Scheme so I made some notes in the form of a timeline.
It includes everything up to R6RS along with the IEEE standard, and publishing of SICP and HtDP. Obviously a lot more things could be added here but I wasn’t trying to take notes for an exhaustive history. All of the sources for the notes can be found in the dot-file below.
