    The long-term goal of the Grothendieck Circle is to make publicly available, and in some cases translate, published and unpublished material written by and about Alexandre Grothendieck, as well as original biographical material and documents. We welcome all spontaneous contributions (of which there have already been many), and hope this site will continue expanding over time.
