Following on from John’s previous post, I’d like to report that The Australasian Journal of Combinatorics (of which I am an editor) has decided to phase out its printed copy and to make all papers freely available online immediately on acceptance.
Therefore, from 2014 onwards, as existing paid-for subscriptions expire, the journal will move to the “free to write, free to read” model that John tells us is called “diamond open access“.
Currently, subscriptions to the journal cover the actual costs, which are primarily printing and postage costs, and generate a small annual surplus (a few thousand dollars), which has accumulated over the years. Eliminating the majority of the costs and all the income will leave a small deficit each year, which can be funded for many years from the accumulated surplus.
It will be interesting to see whether and/or how much things change because of this decision! Obviously, we’re hoping that we can further improve paper quality, with authors appreciating the greater visibility afforded to their papers by immediate online access. To some extent though, its a leap in the dark because we can’t really tell how authors and readers will react. Either way, it will be a valuable experiment.

Congratulations, I fully support this move and any subsequent combinatorics papers I write (like the one I’ve been working on for the past several months) I will pay special consideration to AJC as a potential place to submit 🙂
Congratulations! Wise decision. Authors who want to be read (and which authors don’t?) will prefer to submit their articles to journals with enlightened policies like this.
I add my congratulations to the CMSA committee for taking this decision. Politicians and bureaucrats want to take us down the yellow brick road of author-pays, but with no guarantees that funds will be available for individual mathematicians to get their papers published. Having a successful group of high-quality diamond journals will certainly do us no harm, whatever the future brings.
