As you may remember from an earlier post on this blog, Discrete Analysis is a new mathematics journal that runs just like any other journal except in one respect: the articles we publish live on the arXiv. This is supposed to highlight the fact that in the internet age, and in particular in an age when it is becoming routine for mathematicians to deposit their articles on the arXiv before they submit them to journals, the only important function left for journals is organizing peer review. Since this is done through the voluntary work of academics, it should in principle be possible to run a journal for almost nothing. The legacy publishers (as they are sometimes called) frequently call people naive for suggesting this, so it is important to have actual examples to prove it, and Discrete Analysis is set up to be one such example. Its website goes live today.
