What Is a Museum For? Collecting, Keeping and the Question of Who Owns It

The internationally agreed definition, revised in 2022 after years of argument, describes a permanent institution in the service of society that researches, collects, conserves, interprets and exhibits, and adds that it operates ethically, professionally and with community participation. Each of the five verbs is a department:

• •Collecting, which requires a written policy stating what the institution acquires and why, and the discipline to refuse things outside it, since storage is finite and every object costs money forever
• •Conserving, which is the largest hidden cost: controlled temperature and humidity, light limits, pest management, handling protocols and specialist treatment, all of which are permanent obligations
• •Researching, meaning establishing what an object is, where it came from and what it can tell us, which is what distinguishes a museum from a warehouse
• •Interpreting, meaning deciding what story an object is placed in, which is where the decisions people argue about are actually made
• •Exhibiting, which is the public-facing fraction, and which increasingly rotates because light exposure is cumulative and permanent

The modern museum grows out of the cabinet of curiosities, a private assembly of natural specimens, antiquities and oddities kept by wealthy collectors from the sixteenth century. Several of the great institutions began as one such collection opened to the public: the British Museum was founded in 1753 on the collection of Hans Sloane, whose wealth derived substantially from his wife's interest in Jamaican sugar plantations worked by enslaved people. The nineteenth century turned collecting into a systematic and often official activity, with archaeological expeditions, colonial administrators, military campaigns and scientific surveys sending material back in enormous quantity, and with acquisition frequently conducted under conditions of gross power asymmetry or outright looting. That is not a retrospective judgement in every case, since contemporaries argued about it, and the removal of the Parthenon sculptures by Lord Elgin was contested in Parliament at the time.

The dispute over returning objects is often presented as new and has been running for two centuries. The case for return rests on how the material was taken, on the continuing cultural and religious significance of particular objects to living communities, and on the argument that a people's heritage should be accessible where it was made. The case for retention has been made through the idea of the universal museum, that a collection spanning the world in one place allows comparison and reaches an audience that could not travel, and through practical arguments about conservation capacity and legal title, the latter frequently backed by statutes preventing trustees from disposing of items. The practice has moved substantially: human remains and sacred objects are now routinely returned, French and German institutions have returned significant material to African states, the Benin bronzes taken in a punitive expedition of 1897 have been returned by several museums and universities, and digital reproduction has removed part of the access argument on both sides. The hardest cases involve objects whose acquisition was legal by the standards of the time and coerced in substance.

Funding models shape what an institution can do and say. Publicly funded museums, common in Europe, can offer free entry and are exposed to political pressure and to budget cuts, with real-terms funding in several countries falling substantially since 2010. American museums depend heavily on private donation and endowment, which produces spectacular buildings and gives major donors influence over programming and, at times, over what may be said. Corporate sponsorship has become contested, with sustained campaigns leading several major institutions to end oil company partnerships and to refuse donations from families linked to the opioid trade. Commercial income from ticketing, retail, catering and venue hire has grown and pushes programming toward blockbuster exhibitions that reliably sell, which subsidise the permanent collection and the research nobody buys a ticket for. The common thread is that the parts of the work the public sees are the parts that can be funded, and conservation and cataloguing are perpetually under-resourced.

Several shifts are visible. Interpretation has moved from an authoritative single voice toward acknowledging that a label is an argument, with more institutions stating explicitly how an object was acquired and including the perspectives of the communities it came from. Digitisation has made collections searchable and images freely reusable in a growing number of institutions, which changes what a museum is for when the object can be seen online. Community co-curation involves source communities in deciding how their material is presented. The 2022 definition fight, which took years and several failed votes, was substantially about whether the word decolonising and an explicit social purpose belonged in it, and the compromise text includes community participation and ethical operation without the more contested language. What has not changed is the underlying function, which is to keep things for longer than any individual or company will, and the awkward fact that most of the keeping is invisible and most of the funding follows the part that is not.

A museum displays a small percentage of what it holds, and its core activity is collecting, conserving, researching, interpreting and exhibiting, with conservation the largest hidden cost and a permanent obligation. The great collections were assembled from private cabinets and then through colonial expeditions, administration and military seizure, which is the source of the repatriation dispute, where practice has moved considerably on human remains, sacred objects and the Benin bronzes. Funding model determines programming, and interpretation has shifted from a single authoritative voice toward stating how things were acquired.
