On 7 April 2025, the editorial board of the journal MLQ: Mathematical Logic Quarterly, published by Wiley, has announced its joint resignation. Simultaneously, the Deutsche Vereinigung für Mathematische Logik und für Grundlagenforschung der exakten Wissenschaften (DVMLG) has announced that they will not extend their publishing agreement with Wiley: starting from 2026, the journal MLQ will no longer be published under the auspices of DVMLG.
See here: https://www.dvmlg.de/documents/dvmlg_wiley_openletter.pdf All resigning editors (with the exception of those under contractual obligation with Wiley) have launched a new English-language journal entitled ZML: Zeitschrift für Mathematische Logik und Grundlagen der Mathematik publishing original research papers of high mathematical quality in all areas of mathematical logic, primarily in English. The editors of ZML support true open access removing all barriers to access and believe that the scientific content of research journals must be under the sole control of the academic community and should be free from any commercial or profit-oriented influence. ZML is an electronic Diamond Open Access research journal: the journal is available openly and free of charge to authors and readers anywhere in the world, independently of their institutional affiliations. In the spirit of true open access, all papers are published under the Creative Commons license CC-BY 4.0 International. ZML uses the submission system EditFlow that was designed by mathematicians for mathematicians. Indexing, digital hosting and preservation, as well as assignment of ISSN and DOIs for ZML is provided by Cambridge University Library.
