Here is the latest version of the Primer. We will update this page as newer versions appear. The book is still in the form of a working draft, and so is incomplete and offered without warranty.
Comments/corrections/suggestions are welcomed. If you do send us comments, please let us know which version you are making comments on. Thanks!
We also plan to send announcements of major updates via a mailing list. Click here to subscribe.
A related project is a complete English translation of "Travaux de Thurston". Please contact Dan Margalit if you would like a copy or are interested in helping to edit the current draft.
