There has been a lot of discussion over the last few (in fact, not so few any more) years about problems with academic publishing and what might be done about them. In particular, many mathematicians, including me, are convinced that thanks to the internet there could be a far cheaper system that would give us everything we need from the current system while not bothering with some very expensive aspects that we do not need any more.

One simple idea that has often been raised is that of an arXiv overlay journal. The main characteristic feature of such a journal is that submissions take the form of arXiv preprints. There is some variety in the way the phrase is interpreted beyond that, because there are many choices that can be made about what the journal provides over and above accepting and rejecting papers. So for the purposes of this post let me define a

*pure* arXiv overlay journal to be one for which "publication" consists in nothing more than declaring that an arXiv preprint has been accepted. In principle, such a journal should be very cheap, since its main function is to provide peer review and editorial decisions, which are normally done for no charge by mathematicians themselves.

The blog post linked to is announcing an arXiv overlay journal that I and some other mathematicians have set up. Broadly speaking, it will be in areas that are loosely related to additive combinatorics. To put that pseudo-precisely, if you define a graph with vertices representing areas of mathematics and edges representing pairs of areas of mathematics for which it would not be too surprising to find a mathematician who was an expert in both areas, then this journal will cover not just additive combinatorics but the 1-neighbourhood of additive combinatorics in this graph.

If you are interested in helping the journal to succeed, and perhaps in encouraging the arXiv overlay model to provide a serious challenge to the traditional publishers, then please consider submitting an article (if you work in a relevant area and have a good quality paper) and please spread the word to others who might have a suitable article to submit.

We are accepting submissions now, to a temporary website hosted by Scholastica, an outfit set up by some University of Chicago graduates to make it very easy to set up electronic journals. Early in 2016, we hope to launch the journal, in the sense of going live with a permanent website and a few articles already accepted. The permanent website will again be provided by Scholastica but it will feel more independent. (For example, it will have a URL that is not subsidiary to Scholastica's main URL.)

For more details about the journal and its aims, see the post linked to below. The temporary website mentioned above is here:
