This is a pdf scan of one of the last surviving microfilms of Chomsky’s Logical Structure of Linguistic Theory – all 919 pages of it. While a version of this was published in 1975, that publication omitted several crucial sections, e.g., the information-theoretic analysis of syntactic categories, work done jointly with Peter Elias. In addition, this scan includes Chomsky’s hand-written changes and other marginal notes.
We apologize in advance for the quality of the scan. We thank Noam Chomsky for his permission to post this file, and the Department of Linguistics and Philosophy and Jay Keyser for invaluable help in making this possible.
