<p>This morning I had a brief discussion about different notations of trigonometric functions in Europe, so I looked for an online resource dealing with these diversities in mathematical notation. I found <a href="http://arxiv4.library.cornell.edu/pdf/1004.5165" rel="nofollow">this paper</a> treating the issue. It links to a website called <a href="http://wiki.math-bridge.org/display/ntns/Home" rel="nofollow">Notation census</a> which aims to deal with the diversity by listing the variations in the notation around the world. Still, I find it quite hard to browse the site and feel that lot of things are still not included in its database. Therefore, my question is: do you know of a book or a website compiling these differences in notation in which one can find the most of the non-orthodox symbols and abbreviations used in the world?</p>
