Resignation of MLQ Editorial Board & Launch of new diamond open access journal ZML

On 7 April 2025, the entire editorial board of the journal MLQ: Mathematical Logic Quarterly, published by the commercial publisher Wiley, has announced its resignation since they believe in open science, diamond open access, and the control of journals by the academic community free from profit-oriented interests. Simultaneously, the DVMLG (German logic association) announced that the journal will no longer be published under the auspices of the DVMLG. In the past, the MLQ editorial office was based at the ILLC; ILLC staff member Nick Bezhanishvili is one of the editors who resigned.

Those editors free from contractual obligations with Wiley have launched a new English-language diamond open access journal ZML: Zeitschrift für Mathematische Logik und Grundlagen der Mathematik.
