International Association of Scientific, Technical, and Medical Publishers. The International Association of Scientific, Technical, and Medical Publishers, known for short by the initials for the last part of its name, STM, is an international trade association organised and run for the benefit of scholarly, scientific, technical, medical, and professional publishers. It was conceived as the STM Group at the Frankfurt Book Fair of 1969 following discussions at the 1968 meeting of the International Publishers Association. It obtained its current name and was registered in Amsterdam as a foundation in 1994.
