The German encyclopaedia of artist biographies in 37 volumes with the full title Allgemeines Lexikon der Bildenden Künstler von der Antike bis zur Gegenwart. The joint work contains ca. 250 000 biographies that were compiled with the help of 400 specialists world-wide including all contemporary leading art historians.  The special relevance and strength of the Thieme-Becker-Vollmer lies in entries for less known and almost unknown artists not listed anywhere else; it lies also in the inclusion of architects, designers and other artisans working in applied art.
