Аннотация:Transparency is a crucial aspect of museums that nowadays are expected to be institutions of social trust and social justice.It concerns collections, whose provenances are more often than ever subjected to detailed examinations and whose published results increasingly have consequences, like planned restitutions.But it is also a much wider set of problems caused by museum practices related to colonial pasts that are not closed and often affect the present.One of them is authorship, understood in a wide sense as the privilege of presenting one's own point of view.Transparency also concerns museum policies, such as hiring, acquisition, management, and funding.
