January 2014 — Various photos of conference participants were added to the Centenary Conference page.
November 2013 — Thanks to Ronan Le Roux, who contacted us with scans of four previously unpublished letters that Ross wrote to the French mathematician, Jacques Riguet. We created a Letters from Ross Ashby to Jacques Riguet page, which also includes thumbnails of Journal pages that mention Riguet and help show how Ross was influenced by him.
January 2013 —
In the Biography, a table of contents was added and in the section about the Homeostat, we have added thumbnails of all Journal pages that contain newspaper clippings about the Homeostat.
April 2010 — It appears that we have mistakenly been misrepresenting the An Introduction to Cybernetics PDF as being the second edition. The PDF is the second impression of the first edition.
September 2009 — Transcripts of all summaries that Ross wrote at the end of his journal entries (over 2,300) are available on the Summaries page, and the text of each summary is included above the appropriate journal images and thumbnails.
