Last month’s editorial described the It is gratifying to see more mathematical journals being growing sense among mathematicians published by professional societies and universities. that we may have lost too much Publication of research within the community can be a control over the publication of our collective “right livelihood”, providing societies with work, and some of the initiatives much-needed funds in an appropriate way, as well as a that have been taken to regain that way to keep journal costs under control. We may hope control. This was inspired by a that even the prices of commercially-produced journals discussion on a mathematical mailing list.
