Dr. Robert Berwick and his Computation Linguistics Research group at MIT have digitized a microfilm copy of the marked-up version of Noam Chomsky’s complete thesis draft (1955-56) “The Logical Structure of Linguistic Theory”.
With Chomsky’s permission, the entire file is downloadable at http://alpha-leonis.lids.mit.edu/chomsky/.
This is the copy Chomsky was preparing for publication as ”The Logical Structure of Linguistic Theory”. It contains Chomsky’s hand-written annotations and several chapters and appendices that were left out of the published version of ”The Logical Structure of Linguistic Theory”, including an information-theoretic method to construct linguistic categories that Chomsky developed in conjunction with Peter Elias.
The Logical Structure of Linguistic Theory was published by University of Chicago Press in 1975; we have two copies in Koerner at P158 .C5 1975.
UBC students and faculty also have access to the electronic copy of Chomsky’s 1955 Ph.D dissertation “Transformational Analysis” (which contain a few chapters from this document) through the Proquest Dissertations and Theses database.
