{{Short description|Open-source textbook on algebraic geometry}}

The Stacks Project is an open source collaborative mathematics textbook writing project with the aim to cover "algebraic stacks and the algebraic geometry needed to define them".{{cite web|url=http://stacks.math.columbia.edu/about |title=Stacks Project — About |website=Stacks.math.columbia.edu |date= |accessdate=2020-04-01}}{{Cite web|url=https://www.ams.org/news?news_id=6894|title=Aise Johan de Jong receives 2022 Steele Prize for Mathematical Exposition|website=ams.org|access-date=2021-12-25}}{{cite web|url=https://www.swmath.org/software/31299|title=Stacks Project|website=swmath.org|accessdate=2021-12-25}}{{Cite speech|url=https://www.youtube.com/watch?v=bFTYH1IFaSQ|title=How will we do mathematics in 2030?|first=Michael R.|last=Douglas|location=MIT Center for Brains, Minds & Machines|access-date=2021-12-25}} {{As of|2024|10|23|df=y}}, the book consists of 116 chapters{{cite web|url=http://stacks.math.columbia.edu/browse |title=Stacks Project — Chapters |website=Stacks.math.columbia.edu |date= |accessdate=2020-04-01}} (excluding the license and index chapters) spreading over 7500 pages.
