While at the American Library Association conference in New Orleans this past weekend, I talked with the Springer representative in the exhibits area. During our discussion he told me about the following new search engine Springer has developed:

**LaTeX Search – Mathematical Equations in Scientific Publications**

**http://www.latexsearch.com/**

This new search engine allows one “to search for LaTeX code within scientific publications. LaTeXSearch allows users to locate and view the following:

* Equations containing specific LaTeX code.

* Equations containing LaTeX code that is similar to another LaTeX string.

* All equations belonging to a specific DOI.

* All equations belonging to an article or articles with a particular word or phrase in their title.”

What this means is that the searcher can search for a mathematical expression within all Springer content. This is currently a free search engine, which the rep assured me would always remain free (we’ll see how long that lasts). But anyway, it looks really cool and is a No Brainer. One shouldn’t have to use text to search the mathematical literature any more than one should only be able to search the chemical literature by text (rather than also searching by chemical structure). It seems like the time is right for the ability to search by equation or expression.

According to the about page (http://www.latexsearch.com/static/about.jsp) they are envisioning this eventually including open access content from math preprint and eprint servers like ArXiv.org.

You may want to consider checking this out and letting your math faculty and librarians know about this.
