Project Euclid is a nonprofit scholarly publishing platform focused on mathematics and statistics. Created by Cornell University Library in 2000 and now managed by Duke University Press, it helps independent and small publishers sustain and share important academic research. The platform hosts more than 100 publications from publishers around the world, including journals, books, proceedings, and archival literature across pure and applied mathematics, statistics, probability, computer science, logic, and mathematical physics.

Researchers can browse titles and publishers, search millions of pages using advanced search tools, and access new and archival content. Registered users can save searches, create a favorites list of journals, and customize email alerts; access to some full-text content requires an institutional or society subscription. For libraries, Project Euclid offers subscriptions and access to collections such as Euclid Prime, along with librarian resources. Publishers can use its nonprofit hosting and aggregation services to support dissemination while maintaining their independence. Through these services, Project Euclid connects readers, libraries, and publishers with distinguished mathematical and statistical scholarship.
