Columbia professor Johan de Jong has been compiling the essential theorems of algebraic geometry into one comprehensive resource known as the Stacks Project for the past 15 years. This project, now consisting of over 7,300 pages, revolutionizes the organization and presentation of mathematical information, making it a go-to resource for mathematicians worldwide. In addition, de Jong’s work has inspired similar projects in different mathematical fields. Despite being a massive undertaking, the Stacks Project continues to expand and evolve thanks to its innovative tagging system and a meticulous editing process overseen by de Jong himself. This living document will persist as a valuable resource long into the future.
