Artefacts is an association of historians of science and technology, mostly in museums and academic institutions, who share the goal of promoting the use of objects in serious historical studies. This is done (1) at annual meetings, (2) in a book series, (3) through encouraging the efforts of historically-oriented museums of science and technology. Our next meeting will be in Milan at the Museo Nazionale della Scienza e della Tecnologia Leonardo da Vinci in September 2015. The topic is "Scientific Heritage at World Exhibitions and Beyond. The Long XXth Century." more.
