[Gordon Pask, English cybernetician.] Duplicated privately circulated monograph titled 'A Comment, A Case History and A Plan | by Gordon Pask | System Research Ltd.'

29pp., 4to. Paginated 1-29. Stapled duplicated typescript. In poor condition, with the leaf carrying the first page loose, aged and worn. From the Seymour Papert papers, and with a few notes in pencil (by either Papert or Sonnabend?). No copy found on either COPAC or OCLC WorldCat, nor in Pask's own archive, now in Vienna (Paul Pangaro Pask Collection). The catalogue of the Vienna archive (Furtado/Pangaro) does contain a reference to the article being written prior to the 'Cybernetic Serendipity' exhibition at the ICA in London in 1968, and was published in the following year in a volume of the same name, edited by the exhibition's curator Jasia Reichardt.
