Papers from the Cold Spring Harbor Symposium ('The Genetic Code'), 2-9 June, 1966, for which Crick provided the opening address, subsequently published as "The genetic code - yesterday, today and tomorrow," Cold Spring Harbor Symp. Quant. Biol., 31 (1966), 3-9.
In addition to correspondence and a detailed draft programme for the Symposium, the file contains three sheets of notes (holograph) and a typescript (photocopy, with Crick's name written) of Crick (1966), "The genetic code - yesterday, today and tomorrow." The text begins with the observation: "This is an historic occasion. There have been many meetings about the genetic code during the past ten or twelve years but this is the first important one to be held since the code became known."
Also included in the file are two spiral-bound notebooks:
1. The first notebook (8" x 10") is marked on the front cover "Cold Spring Harbor / 1966" with Crick's name in capital letters. The first part of the notebook comprises a series of short notes on Symposium speakers, beginning with Marshall Nirenberg. The remaining entries (some pages dated 1975) are unrelated horticultural notes, mostly lists of plant varieties.
2. The second notebook (9" x 7") has nothing written on its covers. Beginning with the heading "Probability curve and mean time", there are nine pages (undated) of theoretical notes before this second notebook also takes on a horticultural character (some of these pages dated 1974 and 1975). In the midst of the horticultural notes are further scientific notes (undated, in pencil), one page headed "Notes for a paper", beginning "asymmetric K model".
