March 14, or 3.14, is Pi Day, a day to celebrate all things mathematical. Here at SBU Libraries, we recognize Pi Day by highlighting our resources for your inner Mathlete. For starters, we have subject guides on Mathematics and on our branch Mathematics, Physics, and Astronomy Library. SBU Libraries also provide topical databases such as arXiv , Electronic Library of Mathematics, and MathSciNet. Other mathematical resources include dissertations and theses, and ebooks. At SBU Libraries, access to scholarly resources in mathematics is as easy as pi(e)!
