One million LaTeX math formulas

Springer, one of the largest scientific publishers, announces the launch of, a free online service which makes over 1 million LaTeX equations discoverable. lets users search for LaTeX code in one of three ways:

1) LaTeX Search: Directly typing an equation, in LaTeX, which they would like to find

2) Article title search: Where a user searches against all articles that contain LaTeX

3) Digital Object Identifier (DOI) search: For when a user knows which article they would like to see equations from. is currently powered by a collection of over 120,000 peer- reviewed articles published by Springer, such as Inventiones Mathematicae, Acta Mathematica, and Mathematical Programming. One of the challenges facing readers of mathematics-intensive journals is that they have no way to access the code that generated the equations. solves this problem by giving users multiple ways to find equations and, with one click, access the LaTeX code that generated those equations.

Recognizing that LaTeX's flexibility means users might type the same equation in multiple different ways, Springer invested over eight months in engineering a process that normalizes LaTeX equations. This way, equations that are similar (or even exactly the same but written slightly different) will also appear under the "Similar Results" tab. This ability to provide a comprehensive set of results is unique to and will provide users with the most relevant results possible. is actively soliciting the participation of other publishers and Open Access sources of LaTeX documents to make their equations searchable as well.
