Mathematical Logic Quarterly (MLQ) (formerly: Zeitschrift fuer Mathematische Logik und Grundlagen der Mathematik) is an international journal for the publication of original research papers on mathematical logic, foundations of mathematics and related areas such as General Logic, Model Theory, Recursion Theory, Set Theory, Proof Theory and Constructive Mathematics, Algebraic Logic, Nonstandard Models, and Logical Aspects of Theoretical Computer Science. MLQ is the continuation of the Journal ''Zeitschrift fuer Mathematische Logik und Grundlagen der Mathematik'', founded in 1954 by Guenter Asser and Karl Schroeter. Over the years, many internationally renowed scientists in the field of mathematical research were and are members of the editorial board, their combined efforts are documented in the 44 volumes of the journal comprising more than 1600 original papers by authors from around the world. It is the endeavor of the editorial board that the profil of MLQ reflects the progress in the diverse areas of mathematical logic in a vital manner.
