The goal of this ongoing project is to write an introductory book on statistical
mechanics. As there are already many such books, both for physicists and
mathematicians, we believe it is important to describe what we aim to achieve.
Our plan is to write a book that is

Note [May 11, 2015]: Claudio Landim (IMPA) has recently given a course based on Chapter 3 (The Ising model). Videos of the lectures can be found here (see lectures 1 to 9); the lectures are in Portuguese.

Warning: The chapters below are early drafts. As such, they are likely to contain mistakes and be incomplete (in case you find any mistake, or if you believe that some important topics are missing, please tell us!). Also, bibliographical information may be only partial, or even completely inexistent, depending on the stage of writing.
