When we say recordings are catalogued, we mean the carrier and its contents are described according to established rules that allow an electronic library and discographic database record to be created. The current rules guiding this description will need to be reviewed: based on analysis, the needs of libraries, museums and archive records must be defined, and an optimal set of descriptive metadata structures must be proposed. Cataloguing is an integral part of the process of recording and processing objects owned by an institution. Through cataloguing gramophone records and phonograph cylinders, a full discographic database is created. Within the “New Phonograph” project, the cataloguing of two types of historical media according to relevant RDA standards, in MARC21 format, is ongoing.
