Catalogazione e strumenti terminologici presso il Museo Nazionale della Scienza e della Tecnologia "Leonardo da Vinci" di Milano

Tangible and intangible assets that witness Italian scientific research, technological development and industrial production represent a cultural heritage. Science and technology museums are responsible for the safeguard and the preservation, for the study and the diffusion of such a huge richness, both locally and nationally. The catalogue of the Museo della Scienza e della tecnica \u201cLeonardo da Vinci\u201d in Milan is a enormous collection of specialized terminology, which proves to be necessary to express those areas of science and technology preserved by the Museum. This paper offers an illustration of some terminological records in order to show their level of specialisation. Their study will emphasise the need of a univocal description of objects, as well as the diffusion of the catalogue cultural contents
