How Do Museums Decide What to Keep (And What to Hide)?

What collection management actually covers

Deciding what to collect, what to decline and whether the museum can care for an object over the long term.
Documenting ownership, provenance, cultural context, condition and location so each object can be identified and used responsibly.
Protecting collections through preventive conservation, safe handling, secure storage and emergency planning.
Providing access through exhibitions, loans, research visits and digital catalogues while observing legal, cultural and conservation limits.
Reviewing holdings through provenance work, consultation, deaccession and repatriation when continued possession or unrestricted use is no longer appropriate.

Why collections need written rules

Collection management starts with written policies that define what the museum collects, who may approve decisions and how objects are acquired, recorded, cared for, accessed, transferred or returned. These policies turn professional ethics into daily procedures that staff and governing bodies can apply consistently.

Many museums refer to the International Council of Museums Code of Ethics when setting rules for acquisition, legal compliance, stewardship, access, deaccession and return. ICOM adopted a revised Code of Ethics in June 2026, giving museums a current international reference point for institutional conduct and professional responsibility.

Clear policies also prevent a museum from accepting objects without reliable ownership history, adequate storage, staff expertise or a lawful and ethical reason to keep them. A collection policy should state how provenance concerns are investigated, how culturally sensitive material is handled, when consultation is required and which records must remain after an object leaves the collection.

ICOM’s Working Group on Decolonisation report, published on 16 June 2026, places this work beyond a single act of restitution. It describes decolonisation as an evolving, collective process and presents recommendations drawn from museum practice in different regions. For collection teams, that process can affect acquisition priorities, catalogue language, interpretation, access rules, staff authority, institutional culture and relationships with source communities. Repatriation may form part of the work. The process continues through records, interpretation, access decisions, institutional practice and long-term relationships.

Core steps in collection workflows

To make those rules workable, museums divide collection work into repeatable procedures: object entry, acquisition, documentation, location control, conservation, loans, access, review, deaccession and return. Many institutions use the Spectrum standard, which organises collections work into 21 procedures and provides a shared vocabulary for recording decisions and responsibilities.

Area	Everyday activities	Typical tools
Policy & governance	Writing policies, reviewing collecting priorities, approving loans, sign-off for deaccession.	Board minutes, policy documents, committee terms of reference.
Acquisition & entry	Assessing offers, recording temporary deposits, creating accession records, agreement forms.	Entry forms, due-diligence checklists, acquisition registers.
Documentation	Describing objects, adding photos, updating locations, recording provenance.	Collection Management System (CMS), cataloguing standards, authority files.
Care & conservation	Monitoring climate, rehousing objects, integrated pest management, condition reporting.	Environmental sensors, pest traps, archival boxes, conservation lab.
Access & use	Exhibitions, loans, study visits, digital projects, research access.	Loan agreements, exhibition checklists, online catalogue, image rights database.
Review & change	Collection reviews, provenance research, culturally sensitive access decisions, deaccession and repatriation.	Policy criteria, risk assessments, legal files, consultation records and transfer documentation.

Recording what the museum owns

The first practical task is accessioning: giving each accepted object a unique number and linking it to a basic record. That record identifies who donated, sold or transferred the object, what rights were conveyed, its description, known history and legal status. For culturally sensitive material, it may also record consultation needs, handling limits, display restrictions or possible relevance to a return process. Once accessioned, the museum accepts an ongoing duty of care.

After accessioning, museums build fuller catalogue entries. Staff add dimensions, materials, techniques, cultural context, provenance, condition, previous locations and links to related archives. Shared documentation standards make the information easier to search and compare, while clear notes distinguish verified facts from older attributions or unresolved claims. Without this work, an object may remain physically present but become difficult to identify, interpret, lend or return.

Micro-tasks behind a single record

Check ownership, transfer terms, provenance and permissions.
Assign an accession number and physical label.
Describe the object clearly, marking uncertainty so an assumption is never presented as fact.
Photograph it and link images to the record for quick identification.
Note its exact location, access status and any cultural or legal restrictions.

Modern museums usually store this information in a Collection Management System (CMS), a database designed around museum records, movements, rights and care. Systems such as TMS Collections, MuseumPlus, CollectionSpace and Axiell products can connect object records with locations, rights, loans, conservation, consultation and digital media. They also preserve an audit trail, which matters when a description changes, access is restricted or an object is deaccessioned or repatriated.

Keeping objects safe before they break

Good collection management emphasises preventive conservation: reducing damage before treatment becomes necessary. Museums monitor temperature, relative humidity, light and air quality because unsuitable conditions can accelerate fading, cracking, corrosion or mould growth. Environmental targets depend on the materials, the building and the local climate, but routine monitoring gives staff the evidence needed to respond before visible damage appears.

Museums also control risks from pests, physical forces and handling errors. Staff use integrated pest management to detect insects, design storage that avoids crushing or distortion, and train teams to support weak areas, use suitable trolleys and remove jewellery that could scratch delicate surfaces. A short handling plan and the correct box, mount or support can prevent irreversible loss.

What happens if a label falls off an object in storage? Without good records and photographs, the object can become “orphaned”, separated from its history. This is why many conservators consider documentation itself a form of preventive care.

Standards, checklists and Spectrum

Museums use shared sector standards to avoid designing every procedure from the beginning. The Spectrum collections management standard, maintained by the Collections Trust, covers work from object entry and location control to loans, rights management and deaccession. Spectrum 5.1 reflects both physical and digital collection practice. Accreditation schemes in some countries expect museums to follow selected Spectrum procedures or show how they will reach them.

Teams then adapt those procedures to their staff, buildings and collections. A small community museum may use simple entry forms before adding records to a shared regional database; a large institution may manage millions of records with automated reports, audit tools and APIs. The scale differs, but both need clear responsibilities, consistent terms and an unbroken collection history.

Tracking movement, loans and exhibitions

Every time a museum object moves, there is a risk of loss or damage. Collection managers track locations closely: storage room, shelf, crate, display case, or another institution thousands of kilometres away. They log each move in the CMS, sometimes with barcodes or RFID tags, so the team can see its current location and full movement history.

Loans and exhibitions add more layers. Staff negotiate loan agreements that define responsibilities for insurance, packing, transport and security, and they prepare detailed condition reports before and after travel. These reports often include photos and notes on existing cracks, stains or losses, so any new change is clear. Exhibition teams work with collection managers to choose mounts, lighting and text that show objects safely while still making them engaging for visitors, balancing access with risk.

An object’s exhibition life is also recorded: which shows it appeared in, how often it has been displayed, whether it has light-sensitive materials like dyes or paper, and any limits on future use. This helps curators and conservators decide when to rest an object and when a facsimile or digital image might be a better option for frequent display.

Digital tools and data-driven care

Collection Management Systems have become more powerful in recent years. Many link object records with high-resolution images, conservation notes, exhibition histories and digital assets such as videos or 3D models. Some connect directly to online catalogues, so updates in the internal database quickly refresh public information, reducing duplicated work and keeping details consistent across platforms.

Environmental sensors can also show how storage rooms, cases and buildings behave across seasons. Staff compare those readings with object materials and condition records to decide whether a local enclosure, a change in display time or a building adjustment is needed. The data becomes useful when staff review it, act on it and record the response.

For smaller museums, the immediate task may be moving from paper files or scattered spreadsheets into a structured system. Even a basic, well-maintained database can improve retrieval, enquiries and project planning. The software should match the size of the collection, staff need time to maintain it, and backups and access controls must protect data as carefully as the objects themselves.

Making collections available without ignoring restrictions

Collection management includes public and research access. Objects with reliable records and clear legal status are easier to exhibit, lend, digitise or make available in a study room. Staff can also explain why an object is in storage, how often it may be displayed and what conditions apply to photography, publication or physical handling.

Some material cannot be opened to every visitor or published online without limits. Conservation concerns may restrict light exposure or handling. Copyright, privacy and donor terms may limit reproduction. Sacred or ceremonial material may be governed by community protocols. Human remains, funerary objects and records containing sensitive cultural information may require consultation before access, research, photography or display.

A closed store, withheld image or limited catalogue record can have several causes. The museum should record the reason, who approved the restriction, whether consultation took place and when the decision will be reviewed. An unexplained restriction can conceal poor practice; a documented restriction can protect an object, a person or a community while a lawful process continues.

Digital catalogues add another decision point. Publishing a record may expose an ancestral name, burial location, sacred knowledge, precise archaeological site or image that a source community does not want circulated. Collection managers therefore work with curators, legal staff, conservators and community representatives to decide which information can be public, which should be available only to approved researchers and which should remain restricted.

How decolonisation affects collection decisions

ICOM published the report of its Working Group on Decolonisation on 16 June 2026. The report presents decolonisation as an evolving and collective process shaped by different museum settings and experiences. This places responsibility across the institution, including collections, interpretation, governance, staffing and community relationships.

Within collection work, decolonisation can lead museums to re-examine how objects were acquired, whose knowledge was excluded from catalogue records, which names and classifications came from colonial administration, who controls access and how authority is shared during research and interpretation. It may change collecting priorities, staffing, budgets, storage practice, exhibition language and long-term relationships with source communities.

Return can follow from this work, although other outcomes are also possible: corrected records, community-led interpretation, restrictions on images, renewed cultural care, shared custody, loans, access for ceremony or continued consultation. A museum may hold legal title and still have ethical questions to address about possession, description, display and decision-making.

U.S. Update: How NAGPRA Repatriation Works in 2026

The Native American Graves Protection and Repatriation Act (NAGPRA) creates a specific Federal process for Native American human remains and defined categories of cultural items held by Federal agencies and museums that receive Federal funds. The current regulations are codified at 43 CFR Part 10. It covers:

Human remains of Native American individuals.
Associated funerary objects connected with human remains whose location is known.
Unassociated funerary objects where the related human remains are not in the possession or control of the museum or Federal agency.
Sacred objects needed by traditional Native American religious leaders for present-day practice.
Objects of cultural patrimony that have continuing cultural, traditional or historical importance to an Indian Tribe or Native Hawaiian organization and cannot be alienated, appropriated or conveyed by one individual.

NAGPRA requires museums and Federal agencies to identify relevant holdings and consult with lineal descendants, Indian Tribes and Native Hawaiian organizations. Human remains and associated funerary objects are addressed through an inventory. Unassociated funerary objects, sacred objects and objects of cultural patrimony are addressed through a summary of the holding or collection.

The usual route from records to physical transfer

Identify the holding. Staff examine accession files, catalogues, storage records and other available information to locate human remains or cultural items that may fall under NAGPRA.
Prepare the required inventory or summary. The type of document depends on the category involved and records what the museum or Federal agency knows.
Consult. The institution exchanges information with possible lineal descendants, Indian Tribes and Native Hawaiian organizations and considers traditional knowledge alongside museum documentation.
Publish the required notice. A Notice of Inventory Completion is used for human remains and associated funerary objects. A Notice of Intended Repatriation is used for unassociated funerary objects, sacred objects and objects of cultural patrimony.
Issue a written statement and arrange transfer. After the legal steps are met, the institution relinquishes possession or control, consults on custody and physical transfer, records what was transferred and protects sensitive information as required.

The National Park Service maintains the National NAGPRA Program and public databases for inventories, summaries, grants, Federal Register notices and other compliance records. The database page was updated on 9 June 2026. A museum or Federal agency must submit a Federal Register notice before the disposition or repatriation of human remains or cultural items covered by the Act.

NAGPRA has a defined legal scope and does not cover every disputed museum object. Claims involving stolen art, illegally exported antiquities, wartime seizure, donor ownership or ordinary deaccession may involve different laws, treaties, court procedures and professional standards. NAGPRA applies when the people, institution and material fall within its defined legal scope.

Risk, review and the long view

Collections change over decades. New research may alter an attribution, a storage building may deteriorate and consultation may reveal information absent from the original record. Collection managers use risk assessments and periodic reviews to decide where limited staff time and funding should go. They identify vulnerable material, check which stores need improvement and plan work on packing, shelving, documentation and environmental controls.

Objects may leave the collection through deaccession, restitution or repatriation. Each route has its own authority, evidence and approval requirements. Full documentation should preserve the reason for the decision, the people consulted, the legal or ethical basis, the date of transfer and the location of related files. The object should remain in the historical record after transfer so the institution’s actions remain traceable.

Collection management joins care, knowledge and use through routine work: writing procedures, checking data, reading sensor logs, updating locations, reviewing access and documenting decisions. Reliable records allow future staff, visitors, researchers and source communities to understand what the museum holds, how it obtained it, how it has been used and why it may later be restricted, transferred or returned.
