This is a list of resources available on the web for research mathematicians, updated regularly. The first version was published May 5, 2012. The last update was on June 18, 2013, marked by [UPDATE 13-06-18].
If you have any recommendations on what to add to this list, please leave a comment below.
Reference & Bibliography tools
Doing research (and even preparing seminar talks), you need to check the available literature. There are many tools to do this, most notably MathSciNet to get correct bibliographic data, reviews of articles and links to journals to download articles, if possible.
- MathSciNet Mathematical Reviews (MR), paper reviews (subscription required).
- MathSciNet Lookup, bibliographic information (no subscription required).
- Zentralblatt MATH (Zbl), paper reviews.
- Google Scholar, a citation search engine.
- The Selected Papers Network, a federated approach to reviewing and discussing articles and preprints. [UPDATE 13-06-18]
- Eigenfactor, a website with tools to work with "new" metrics.
- Mendeley's mathematics section - Mendely is a reference management tool.
- CiteSeer, a citation search engine.
- RetractionWatch mathematics section - RetractionWatch is tracking retractions as a window into the scientific process.
- Allyn Jackson: From Preprints to E-prints (AMS Notices 2002, PDF)
- JabRef, an open source bibliography manager (written in Java).
- Nature Special: Science Metrics, like citation count, eigenfactor and h-index.
- Bookworm arXiv, search for trends in the arXiv.
- Google Books NGram Viewer, to see when a specific term was used a lot.
Open Access Journals & Preprint Archives
Nowadays many publications are discussed as soon as they reach a preprint archive, or an e-print archive. It can take years until journal publication of a preprint, so you will most likely work with preprints anyway.

Notable Math Blogs
I warmly recommend clicking through this list and then through the blogrolls of each blog, until you found your niche in the blogosphere. There are vast amounts of content, and there is always some quality content hidden, deep inside. It is really worthwile to search once and to grab the RSS feeds of the 2-3 most interesting blogs. I also recommend to browse through the archives of interesting blogs, sometimes an article from some years ago might inspire you!

The Cost of Knowledge - The Academic Spring
In January 2012, Fields medallist Timothy Gowers wrote a blog post about the academic publisher Elsevier, its bad business practices and that he decided to boycott them. This lead to the creation of a boycott movement website "The Cost of Knowledge" and a discussion forum to change the world of mathematical publishing. The Academic Spring it was called.
- T.Gowers: Elsevier — my part in its downfall.
- the cost of knowledge (dot com)
- Math2.0 Forum, a place to discuss publishing.
- Rehmann's Math Journal Price Survey.
- J.C.Baez: What We Can Do About Science Journals.
- M.Nielsen's comprehensive linklist on the academic spring, really a good starting point to get involved.

How to give a talk
Beware that there are many kinds of mathematics talks: seminar talks (audience should understand), workshop talks (experts should understand), colloquium talks (mathematicians should understand most), general public talks (non-mathematicians should understand most) - and all mixtures of these. Most talks take about 45 up to 90 minutes, although some plan only 20 to 30 minutes. It is crucial to know what kind of talk is expected and who the audience is. Besides that ... there are some tips & tricks:
- Matilde Marcolli: The (Martial) Art of Giving Talks, (PDF).
- William T. Ross: How to give a good 20-minute talk
- John E. McCarthy: How to Give a Good Colloquium (PDF)
- P.R. Halmos: How to talk Mathematics, a classic
- Joseph A. Gallian: How to Give a Good Talk, comes with a handy preparation check-list (PDF).
- David Tong: How to Make Sure Your Talk Doesn’t Suck (PDF)
- Read the AMS Notices, in particular the "What is ..." series. It is very good at explaining concepts to the general mathematical public.
How to fail graduate school / obtaining a PhD
Inspired by this MO thread, but mostly stuff I actually read and can recommend. Most of these advice articles seem to think of the US system, where you stay in grad school for a while and then look for an advisor, while it's different in many other countries. However, much advice is useful, and I recommend to read it early on, before entering anything similar to grad school at all!
- Scott Hanselman: It's not what you read, it's what you ignore (not particularly for mathematicians, more for programmers, but still valuable)
- Bob L. Sturm: 25 points for PhD students
- Marie desJardins: How to Be a Good Graduate Student (for computer scientists)
- Secret Blogging Seminar: Thoughts on Graduate School - read the comments!
- Secret Blogging Seminar: Thoughts on Graduate School, addendum
- Terence Tao's career advice
- Ravi Vakil's career advice comes with many links
How to write mathematics teXnically
If you have to write math, you either do it on paper, on a blackboard or on a computer.
On any computer, you'll likely use LaTeX, since the days of trying to use ASCII are long over.
LaTeXing is an art to be learned, but the basics are pretty easy and it's no longer limited to creating PS or PDF files, but you can literally TeX the web.
- TeX StackExchange, the question-answer forum.
- TeXample.net, ample resources for TeX users, especially for TikZ graphics.
- XyJax, an enhancement of MathJax to support (large parts of) xypic.
- HTML escape codes for math | HTML escape codes for greek letters
- LaTeX for WordPress Plug-in, the one I currently use (implemented with MathJax).
- Instiki, a wiki that supports LaTeX+Markdown syntax (implemented in Ruby, with MathJax)
- Detexify - LaTeX symbol classifier, you draw a math symbol with your mouse pointer, then you get LaTeX code.
- MathJax Bookmarklet, to enable LaTeX rendering via MathJax on any website.
- ShareLaTeX - Real Time LaTeX Collaboration is a LaTeX-enabled cloud document editor. [UPDATE 13-02-04]
Some conference & summer school listings
You should choose which one is most useful to you, then check that one more often and maybe ignore the rest.
- Meetings and Conferences of the AMS
- Andreas Holmstrom's list of lists
- K-Theory Calendar
- Conferences in Arithmetic Geometry
- Conferences and meetings on Topology and related topics
- Upcoming conferences in algebraic geometry
They still exist. And they're mostly used for job offers and conference announcements.
