Developed and deployed by Cornell University Library and managed by Cornell and Duke University Press, Project Euclid is a not-for-profit online publishing service that provides access to journals, monographs, and conference proceedings in the fields of theoretical and applied mathematics and statistics. Its mission is to advance scholarly communication in these fields and it is designed to address the unique needs of low-cost independent and society journals. Through a collaborative partnership arrangement, these publishers join forces and participate in an online presence with advanced functionality, without sacrificing their intellectual or economic independence or commitment to low subscription prices. Full-text searching, reference linking, interoperability through the Open Archives Initiative, and long-term retention of data are all important components of the project. Search results provide links to other issues in the source journal along with links to relevant keywords and subject codes, allowing users to expand their search. Users may also browse individual journals by title, publisher, or subject area, and browse conference proceedings or monographs by title; the level of access is conveniently color coded for each title.
