The Stacks project is “an open source textbook and reference work on algebraic geometry” that has been consistently growing since 2008. At the time of writing, the material encompasses more than 7500 pages, and it is regularly expanded. It contains background material in commutative algebra and algebraic geometry, advanced material, and even previously unpublished work. Widely used as a reference in algebraic geometry, the Stacks project is most easily accessed via its website

https://stacks.math.columbia.edu

The project is collaborative, with more than 500 contributors, listed on the website. Every submission and comment is reviewed carefully, for correctness and coherence with the rest of the text, by the second editor of this volume.
