Collection activities, including acquisition, registration, cataloguing, conservation, inventory, and use of collections for exhibition and education, are fundamental and critical functions of a museum. Procedural standards are used to describe the definitions and processes of these activities. With the development of digital archives/collections, procedural standards are considered a type of information standard. However, there is a significant difference between procedural and information standards among museums. There is also a lack of systematic exploration of existing procedural standards among museum communities. The aims of this article are to explore museum procedural standards and to discuss what makes them differ from information standards. In addition, existing procedural standards in international museum communities are classified and compared. Finally, suggestions for procedural standards in museum communities are offered.
