CIDOC fact sheets are produced to disseminate, in a simple format, information on aspects of museum documentation. This fact sheet is concerned with the methods used for labelling and marking of objects with their accession or inventory number. The methods to apply the number to the object are not always agreed upon. However, there are some rules generally accepted in the museum community. As this fact sheet can only give summerised information, it concludes with some literature for further reading.
