Mathematics Research Guide: Useful Websites

Eric Weisstein's World of Mathematics (MathWorldTM) is the web's most complete mathematics resource, assembled over more than a decade by internet encyclopedist Eric W. Weisstein with assistance from the mathematics and internet communities. MathWorld is a convenient, comprehensive, and interactive mathematics encyclopedia intended for students, educators, math enthusiasts, and researchers. Like the vibrant and constantly evolving discipline of mathematics, this site is continuously updated to include new material and incorporate new discoveries.

Online database of over 220,000 sequences. Each entry contains the leading terms of the sequence, keywords, mathematical motivations, literature links, and more, including the option to generate a graph or play a musical representation of the sequence.

A resource comprising the world's most encyclopedic collection of information about mathematical functions.

Open access to 554,760 e-prints in Physics, Mathematics, Computer Science, Quantitative Biology, Quantitative Finance and Statistics.

Provides access to preprints from many European authors and institutions.

E-Print Network is a searchable, "integrated network of electronic scientific and technical information created by scientists and research engineers active in their respective fields, intended for use by other scientists, engineers, and students at advanced levels." The discipline of Mathematics is included.
