The Journal of Mathematical Philosophy is a new open-access journal.

According to an announcement from its editors, the journal is “the first open access journal that is devoted to mathematical philosophy.”
It is now open to submissions in subject areas such as as formal epistemology, philosophical logic, philosophy of science, decision theory, philosophy of mathematics, formal metaphysics, philosophy of language, formal ethics, and philosophy of AI.
Published by LMU Munich, the Journal of Mathematical Philosophy is a “diamond” open-access journal, meaning that there are no author fees nor reader fees. The journal will make use of double-anonymous reviewing.
The journal is led by co-editors-in-chief Jürgen Landes and Lennart Ackermans, both of LMU Munich.
The inaugural associate editors are Francesca Zaffora Blando, Thomas Boyer-Kassem, Justin Bruner, Lorenzo Casini, Gustavo Cevolani, Kenny Easwaran, Ben Eva, Branden Fitelson, Sam Fletcher, Alexander Gebharter, Conrad Heilmann, Bennet Holman, Ekaterina Kubyshkina, Stephan Leuenberger, Conor Mayo-Wilson, Mattia Petrolo, Giuseppe Primero, Saeed Salehi, Jonah Schupbach, Dunja Šešelja, Ted Shear, Eric Snyder, Reuben Stern, Rush Stewart, Christian Strasser, David Teira, Brout Trpin, Olav Vassend, and Sylvia Wenmakers. The inaugural advisory board consists of Michael Glanzberg, Stephan Hartmann, Jan-Willem Romeijn, Jacob Stegenga, and Edward Zalta.

I’ve been receiving Lorenzo Cassini’s papers at 3 am EST for years! I’m in!
Fantastic news. Diamond Open Access supported by a faculty and/or university library is the best way to run a journal.
Oddly but pleasingly, I’ve found that the easiest journals to interact with as a submitting author have used this model (Ergo, PhiMiSci, Theoria). Long may this trend continue.
Hopefully shorter times from acceptance to publication than Ergo…
Not meaning to pick a fight here, but time from acceptance to publication is probably the least thing I care about in a journal.
Absolutely. I mean, once you put it on your CV (at the point of acceptance), who cares when it’s even published. what’s important is the time between submitting and getting a verdict.
I don’t publish for an extra line on my CV.
But as long as it’s on PhilPapers with “forthcoming in [Journal X]”, you’ve got everything that matters for everyone except people who refuse to read things until they have the journal name inside the document.
Sure, sure… Why do journals even publish at all?!
For the line on your c.v.!
Sadly, some place (I’m looking around at myself in Australia right now) have both lots of pressure to publish all the time, and also don’t “count” things until they are at least “on line first”, so if something is still waiting in the queue to be “on line first”, it may not do you good. (You might note that it will do you good in the future, and that’s true, but where I worked the first five years in Australia, one’s teaching load was adjusted each year based on the last couple of years of publishing, so not having something “come out” in a timely way might well lead to a greatly increased teaching load, which of course makes future publishing hard… )
Following on what Matt L said, in some places, you don’t receive credit from the university until the article has been officially published, as in assigned an issue and page numbers. This happens at some universities in Asia and in New Zealand. Time
That’s a reason to care, I agree. It’s a pretty uncommon reason, I think, and more a problem with some university admins’ policies rather than a problem with the journal itself.
Let’s not blame Ergo for the fault of others, over something that most — not all, but most — have no real reason to care about. We need more journals like Ergo, not fewer, and if long wait times from acceptance to publication is the cost then that’s worth it.
In North America (at least the US and Canada), it is common to get credit for an article once it is accepted. In other parts of the world, one may not get credit until a later time in the publication process, either online first or page numbers assigned.
No one is saying that there should be no diamond open access journals because Ergo takes a long time to publish articles. It is worth bearing in mind that the long wait times for publication do affect authors and can affect where they submit papers. Further, it seems totally fine to criticize Ergo, and other journals, for taking a long time to get things through the publication pipeline, particularly if it materially affects one’s job.
Exactly. And, at the risk of having to state the obvious, this is just on reason among many why time from acceptance to publication matters. (For a discipline that is largely a priori in its methods, some colleagues seem pretty bad at using their imagination.)
