THE ARCHIVE / CHANGES OVER TIME
The RSPS timeline.
A record of projects, communities and technical changes. Exact dates are shown only when supported; approximate periods stay approximate.
Putting the dates on the record.
The first milestones are being checked against surviving sources. The timeline will appear here as that work is published.
Our archive distinguishes original documentation, contemporary discussion and later recollection. A popular retelling alone does not establish an exact date.
