Documentation is essential to all aspects of a museums activities. Collections without adequate documentation are not true "museum" collections.
CIDOC, ICOM's International Committee for Documentation, provides the museum community with advice on good practice and developments in museum documentation.
CIDOC is one of the 30 International committees of ICOM. It is CIDOC rather than ICDOC because the committee was at its inception guided by mostly Francophones (French speakers) who named it the Comité International de la Documentation. As the world has become more Anglophone (English speaking) the lingua franca of the committee has become English, and the de facto name has become the International Committee for Documentation.
One of the tasks of Documentalists is to aid in the recording of such linguistic mutations such that the committee and its work can be found and understood by all, no matter what language they use.
