A museum ( ; plural museums or, rarely, musea) is a building or institution that cares for and displays a collection of artifacts and other objects of artistic, cultural, historical, or scientific importance. Many public museums make these items available for public viewing through exhibits that may be permanent or temporary. The largest museums are located in major cities throughout the world, while thousands of local museums exist in smaller cities, towns, and rural areas. Museums have varying aims, ranging from the conservation and documentation of their collection, serving researchers and specialists, to catering to the general public. The goal of serving researchers is not only scientific, but intended to serve the general public.

There are many types of museums, including art museums, natural history museums, science museums, war museums, and children's museums. According to the International Council of Museums (ICOM), there are more than 55,000 museums in 202 countries.

Etymology

The English "museum" comes from the Latin word, and is pluralized as "museums" (or rarely, "musea"). It is originally from the Ancient Greek Μουσεῖον (''Mouseion''), which denotes a place or temple dedicated to the muses (the patron divinities in Greek mythology of the arts), and hence was a building set apart for study and the arts, especially the Musaeum (institute) for philosophy and research at Alexandria, built under Ptolemy I Soter about 280 BC.

Purpose

The purpose of modern museums is to collect, preserve, interpret, and display objects of artistic, cultural, or scientific significance for the study and education of the public. From a visitor or community perspective, this purpose can also depend on one's point of view. A trip to a local history museum or large city art museum can be an entertaining and enlightening way to spend the day. To city leaders, an active museum community can be seen as a gauge of the cultural or economic health of a city, and a way to increase the sophistication of its inhabitants. To a museum professional, a museum might be seen as a way to educate the public about the museum's mission, such as civil rights or environmentalism. Museums are, above all, storehouses of knowledge. In 1829, James Smithson's bequest, that would fund the Smithsonian Institution, stated he wanted to establish an institution "for the increase and diffusion of knowledge".

Museums of natural history in the late 19th century exemplified the scientific desire for classification and for interpretations of the world. Gathering all examples for each field of knowledge for research and display was the purpose. As American colleges grew in the 19th century, they developed their own natural history collections for the use of their students. By the last quarter of the 19th century, scientific research in universities was shifting toward biological research on a cellular level, and cutting-edge research moved from museums to university laboratories. While many large museums, such as the Smithsonian Institution, are still respected as research centers, research is no longer a main purpose of most museums. While there is an ongoing debate about the purposes of interpretation of a museum's collection, there has been a consistent mission to protect and preserve cultural artifacts for future generations. Much care, expertise, and expense is invested in preservation efforts to retard decomposition in aging documents, artifacts, artworks, and buildings. All museums display objects that are important to a culture. As historian Steven Conn writes, "To see the thing itself, with one's own eyes and in a public place, surrounded by other people having some version of the same experience, can be enchanting."

Museum purposes vary from institution to institution. Some favor education over conservation, or vice versa. For example, in the 1970s, the Canada Science and Technology Museum favored education over preservation of their objects. They displayed objects as well as their functions. One exhibit featured a historical printing press that a staff member used for visitors to create museum memorabilia. Some museums seek to reach a wide audience, such as a national or state museum, while others have specific audiences, like the LDS Church History Museum or local history organizations. Generally speaking, museums collect objects of significance that comply with their mission statement for conservation and display. Apart from questions of provenance and conservation, museums take into consideration the former use and status of an object. Religious or holy objects, for instance, are handled according to cultural rules. Jewish objects that contain the name of God may not be discarded, but need to be buried.

Although most museums do not allow physical contact with the associated artifacts, there are some that are interactive and encourage a more hands-on approach. In 2009, Hampton Court Palace, a palace of Henry VIII, in England opened the council room to the general public to create an interactive environment for visitors. Rather than allowing visitors to handle 500-year-old objects, however, the museum created replicas, as well as replica costumes. The daily activities, historic clothing, and even temperature changes immerse the visitor in an impression of what Tudor life may have been.

Definitions by major museum professional organizations

Major museum professional organizations from around the world offer some definitions as to what a museum is and their purpose. Common themes in all the definitions are public good and care, preservation, and interpretation of collections.

The International Council of Museums' current definition of a museum (adopted in 2022): "A museum is a not-for-profit, permanent institution in the service of society that researches, collects, conserves, interprets and exhibits tangible and intangible heritage. Open to the public, accessible and inclusive, museums foster diversity and sustainability. They operate and communicate ethically, professionally and with the participation of communities, offering varied experiences for education, enjoyment, reflection and knowledge sharing."

The Canadian Museums Association's definition: "A museum is a non-profit, permanent establishment, that does not exist primarily for the purpose of conducting temporary exhibitions and that is open to the public during regular hours and administered in the public interest for the purpose of conserving, preserving, studying, interpreting, assembling and exhibiting to the public for the instruction and enjoyment of the public, objects and specimens or educational and cultural value including artistic, scientific, historical and technological material."

The United Kingdom's Museums Association's definition: "Museums enable people to explore collections for inspiration, learning and enjoyment. They are institutions that collect, safeguard and make accessible artifacts and specimens, which they hold in trust for society."

While the American Alliance of Museums does not have a definition their list of accreditation criteria to participate in their Accreditation Program states a museum must: "Be a legally organized nonprofit institution or part of a nonprofit organization or government entity; Be essentially educational in nature; Have a formally stated and approved mission; Use and interpret objects or a site for the public presentation of regularly scheduled programs and exhibits; Have a formal and appropriate program of documentation, care, and use of collections or objects; Carry out the above functions primarily at a physical facility or site; Have been open to the public for at least two years; Be open to the public at least 1,000 hours a year; Have accessioned 80 percent of its permanent collection; Have at least one paid professional staff with museum knowledge and experience; Have a full-time director to whom authority is delegated for day-to-day operations; Have the financial resources sufficient to operate effectively; Demonstrate that it meets the Core Standards for Museums; Successfully complete the Core Documents Verification Program"

Additionally a there is a legal definition of museum in United States legislation in the authorizing the establishment of the Institute of Museum and Library Services: "Museum means a public, tribal, or private nonprofit institution which is organized on a permanent basis for essentially educational, cultural heritage, or aesthetic purposes and which, using a professional staff: Owns or uses tangible objects, either animate or inanimate; Cares for these objects; and Exhibits them to the general public on a regular basis." (Museum Services Act 1976)

History

Ancient history

One of the oldest museums known is Ennigaldi-Nanna's museum, built by Princess Ennigaldi in modern Iraq at the end of the Neo-Babylonian Empire. The site dates from c. 530 BCE, and contained artifacts from earlier Mesopotamian civilizations. Notably, a clay drum label—written in three languages—was found at the site, referencing the history and discovery of a museum item.

Ancient Greeks and Romans collected and displayed art and objects but perceived museums differently from modern day views. In the classical period the museums were the temples and their precincts which housed collections of votive offerings. Paintings and sculptures were displayed in gardens, forums, theaters, and bathhouses. In the ancient past there was little differentiation between libraries and museums with both occupying the building and were frequently connected to a temple or royal palace. The Museum of Alexandria is believed to be one of the earliest museums in the world. While it connected to the Library of Alexandria it is not clear if the museum was in a different building from the library or was part of the library complex. While little was known about the museum it was an inspiration for museums during the early Renaissance period. The royal palaces also functioned as a kind of museum outfitted with art and objects from conquered territories and gifts from ambassadors from other kingdoms allowing the ruler to display the amassed collections to guests and to visiting dignitaries.

Also in Alexandria from the time of Ptolemy II Philadelphus (r. 285-246 BCE), was the first zoological park. At first used by Philadelphus in an attempt to domesticate African elephants for use in war, the elephants were also used for show along with a menagerie of other animals specimens including hartebeests, ostriches, zebras, leopards, giraffes, rhinoceros, and pythons.

Early history

Early museums began as the private collections of wealthy individuals, families or institutions of art and rare or curious natural objects and artifacts. These were often displayed in so-called "wonder rooms" or cabinets of curiosities. These contemporary museums first emerged in western Europe, then spread into other parts of the world.

Public access to these museums was often possible for the "respectable", especially to private art collections, but at the whim of the owner and his staff. One way that elite men during this time period gained a higher social status in the world of elites was by becoming a collector of these curious objects and displaying them. Many of the items in these collections were new discoveries and these collectors or naturalists, since many of these people held interest in natural sciences, were eager to obtain them. By putting their collections in a museum and on display, they not only got to show their fantastic finds but also used the museum as a way to sort and "manage the empirical explosion of materials that wider dissemination of ancient texts, increased travel, voyages of discovery, and more systematic forms of communication and exchange had produced".

One of these naturalists and collectors was Ulisse Aldrovandi, whose collection policy of gathering as many objects and facts about them was "encyclopedic" in nature, reminiscent of that of Pliny, the Roman philosopher and naturalist. The idea was to consume and collect as much knowledge as possible, to put everything they collected and everything they knew in these displays. In time, however, museum philosophy would change and the encyclopedic nature of information that was so enjoyed by Aldrovandi and his cohorts would be dismissed as well as "the museums that contained this knowledge". The 18th-century scholars of the Age of Enlightenment saw their ideas of the museum as superior and based their natural history museums on "organization and taxonomy" rather than displaying everything in any order after the style of Aldrovandi.

The first "public" museums were often accessible only by the middle and upper classes. It could be difficult to gain entrance. When the British Museum opened to the public in 1759, it was a concern that large crowds could damage the artifacts. Prospective visitors to the British Museum had to apply in writing for admission, and small groups were allowed into the galleries each day. The British Museum became increasingly popular during the 19th century, amongst all age groups and social classes who visited the British Museum, especially on public holidays.

The Ashmolean Museum, however, founded in 1677 from the personal collection of Elias Ashmole, was set up in the University of Oxford to be open to the public and is considered by some to be the first modern public museum. The collection included that of Elias Ashmole which he had collected himself, including objects he had acquired from the gardeners, travellers and collectors John Tradescant the elder and his son of the same name. The collection included antique coins, books, engravings, geological specimens, and zoological specimens—one of which was the stuffed body of the last dodo ever seen in Europe; but by 1755 the stuffed dodo was so moth-eaten that it was destroyed, except for its head and one claw. The museum opened on 24 May 1683, with naturalist Robert Plot as the first keeper. The first building, which became known as the Old Ashmolean, is sometimes attributed to Sir Christopher Wren or Thomas Wood.
In France, the first public museum was the Louvre Museum in Paris, opened in 1793 during the French Revolution, which enabled for the first time free access to the former French royal collections for people of all stations and status. The fabulous art treasures collected by the French monarchy over centuries were accessible to the public three days each "''décade''" (the 10-day unit which had replaced the week in the French Republican Calendar). The ''Conservatoire du muséum national des Arts'' (National Museum of Arts's Conservatory) was charged with organizing the Louvre as a national public museum and the centerpiece of a planned national museum system. As Napoléon I conquered the great cities of Europe, confiscating art objects as he went, the collections grew and the organizational task became more and more complicated. After Napoleon was defeated in 1815, many of the treasures he had amassed were gradually returned to their owners (and many were not). His plan was never fully realized, but his concept of a museum as an agent of nationalistic fervor had a profound influence throughout Europe.

Chinese and Japanese visitors to Europe were fascinated by the museums they saw there, but had cultural difficulties in grasping their purpose and finding an equivalent Chinese or Japanese term for them. Chinese visitors in the early 19th century named these museums based on what they contained, so defined them as "bone amassing buildings" or "courtyards of treasures" or "painting pavilions" or "curio stores" or "halls of military feats" or "gardens of everything". Japan first encountered Western museum institutions when it participated in Europe's World's Fairs in the 1860s. The British Museum was described by one of their delegates as a 'hakubutsukan', a 'house of extensive things' – this would eventually become accepted as the equivalent word for 'museum' in Japan and China.

Modern history

American museums eventually joined European museums as the world's leading centers for the production of new knowledge in their fields of interest. A period of intense museum building, in both an intellectual and physical sense was realized in the late 19th and early 20th centuries (this is often called "The Museum Period" or "The Museum Age"). While many American museums, both natural history museums and art museums alike, were founded with the intention of focusing on the scientific discoveries and artistic developments in North America, many moved to emulate their European counterparts in certain ways (including the development of Classical collections from ancient Egypt, Greece, Mesopotamia, and Rome). Drawing on Michel Foucault's concept of liberal government, Tony Bennett has suggested the development of more modern 19th-century museums was part of new strategies by Western governments to produce a citizenry that, rather than be directed by coercive or external forces, monitored and regulated its own conduct. To incorporate the masses in this strategy, the private space of museums that previously had been restricted and socially exclusive were made public. As such, objects and artifacts, particularly those related to high culture, became instruments for these "new tasks of social management". Universities became the primary centers for innovative research in the United States well before the start of World War II. Nevertheless, museums to this day contribute new knowledge to their fields and continue to build collections that are useful for both research and display.

The late twentieth century witnessed intense debate concerning the repatriation of religious, ethnic, and cultural artifacts housed in museum collections. In the United States, several Native American tribes and advocacy groups have lobbied extensively for the repatriation of sacred objects and the reburial of human remains. In 1990, Congress passed the Native American Graves Protection and Repatriation Act (NAGPRA), which required federal agencies and federally funded institutions to repatriate Native American "cultural items" to culturally affiliate tribes and groups. Similarly, many European museum collections often contain objects and cultural artifacts acquired through imperialism and colonization. Some historians and scholars have criticized the British Museum for its possession of rare antiquities from Egypt, Greece, and the Middle East.

Management

The roles associated with the management of a museum largely depend on the size of the institution. Together, the Board and the Director establish a system of governance that is guided by policies that set standards for the institution. Documents that set these standards include an institutional or strategic plan, institutional code of ethics, bylaws, and collections policy. The American Alliance of Museums (AAM) has also formulated a series of standards and best practices that help guide the management of museums.

* Board of Trustees or Board of directors – The board governs the museum and is responsible for ensuring the museum is financially and ethically sound. They set standards and policies for the museum. Board members are often involved in fundraising aspects of the museum and represent the institution.Hugh H. Genoways and Lynne M. Ireland, ''Museum Administration: An Introduction'', (Lanham: AltaMira, 2003), 3. Some museum use the terms "directors" and "trustees" interchangeably but both are different legal instruments. A board of directors governs a nonprofit corporation, a board of trustees is responsible for governing a charitable trust, foundation, or endowment. In the case of small museums and all volunteer museums, a board may be more hands-on in the day-to-day operations of the museum.
* Director- The director is the face of the museum to the professional and public community. They communicate closely with the board to guide and govern the museum. They work with the staff to ensure the museum runs smoothly. According to museum professionals Hugh H. Genoways and Lynne M. Ireland, "Administration of the organization requires skill in conflict management, interpersonal relations, budget management and monitoring, and staff supervision and evaluation. Managers must also set legal and ethical standards and maintain involvement in the museum profession."

Various positions within the museum carry out the policies established by the Board and the Director. All museum employees should work together toward the museum's institutional goal. Here is a list of positions commonly found at museums:
* Curator – Curators are the intellectual drivers behind exhibits. They research the museum's collection and topic of focus, develop exhibition themes, and publish their research aimed at either a public or academic audience. Larger museums have curators in a variety of areas. For example, The Henry Ford has a Curator of Transportation, a Curator of Public Life, a Curator of Decorative Arts, etc. Many art museums have curators dedicated to specific historic periods and geographic regions, such as American art and modern or contemporary art.
* Collections Management – Collections managers are primarily responsible for the hands-on care, movement, and storage of objects. They are responsible for the accessibility of collections and collections policy.
* Registrar – Registrars are the primary record keepers of the collection. They insure that objects are properly accessioned, documented, insured, and, when appropriate, loaned. Ethical and legal issues related to the collection are dealt with by registrars. Along with collections managers, they uphold the museum's collections policy.
* Educator – Museum educators are responsible for educating museum audiences. Their duties can include designing tours and public programs for children and adults, teacher training, developing classroom and continuing education resources, community outreach, and volunteer management. Educators not only work with the public, but also collaborate with other museum staff on exhibition and program development to ensure that exhibits are audience-friendly.
* Exhibit Designer – Exhibit designers are in charge of the layout and physical installation of exhibits. They create a conceptual design and then bring it to fruition in the physical space.
* Conservator – Conservators focus on object restoration. More than preserving the object in its present state, they seek to stabilize and repair artifacts to the condition of an earlier era.

Other positions commonly found at museums include: building operator, public programming staff, photographer, librarian, archivist, groundskeeper, volunteer coordinator, preparator, security staff, development officer, membership officer, business officer, gift shop manager, public relations staff, and graphic designer.

At smaller museums, staff members often fulfill multiple roles. Some of these positions are excluded entirely or may be carried out by a contractor when necessary.

Protection

The cultural property stored in museums is threatened in many countries by natural disaster, war, terrorist attacks or other emergencies. To this end, an internationally important aspect is a strong bundling of existing resources and the networking of existing specialist competencies in order to prevent any loss or damage to cultural property or to keep damage as low as possible. International partner for museums is UNESCO and Blue Shield International in accordance with the Hague Convention for the Protection of Cultural Property from 1954 and its 2nd Protocol from 1999. For legal reasons, there are many international collaborations between museums, and the local Blue Shield organizations.

Blue Shield has conducted extensive missions to protect museums and cultural assets in armed conflict, such as 2011 in Egypt and Libya, 2013 in Syria and 2014 in Mali and Iraq. During these operations, the looting of the collection is to be prevented in particular.

Planning

The design of museums has evolved throughout history. However, museum planning involves planning the actual mission of the museum along with planning the space that the collection of the museum will be housed in. Intentional museum planning has its beginnings with the museum founder and librarian John Cotton Dana. Dana detailed the process of founding the Newark Museum in a series of books in the early 20th century so that other museum founders could plan their museums. Dana suggested that potential founders of museums should form a committee first, and reach out to the community for input as to what the museum should supply or do for the community. According to Dana, museums should be planned according to community's needs:

"The new museum ... does not build on an educational superstition. It examines its community's life first, and then straightway bends its energies to supplying some the material which that community needs, and to making that material's presence widely known, and to presenting it in such a way as to secure it for the maximum of use and the maximum efficiency of that use."

The way that museums are planned and designed vary according to what collections they house, but overall, they adhere to planning a space that is easily accessed by the public and easily displays the chosen artifacts. These elements of planning have their roots with John Cotton Dana, who was perturbed at the historical placement of museums outside of cities, and in areas that were not easily accessed by the public, in gloomy European style buildings.

Questions of accessibility continue to the present day. Many museums strive to make their buildings, programming, ideas, and collections more publicly accessible than in the past. Not every museum is participating in this trend, but that seems to be the trajectory of museums in the twenty-first century with its emphasis on inclusiveness. One pioneering way museums are attempting to make their collections more accessible is with open storage. Most of a museum's collection is typically locked away in a secure location to be preserved, but the result is most people never get to see the vast majority of collections. The Brooklyn Museum's Luce Center for American Art practices this open storage where the public can view items not on display, albeit with minimal interpretation. The practice of open storage is all part of an ongoing debate in the museum field of the role objects play and how accessible they should be.

In terms of modern museums, interpretive museums, as opposed to art museums, have missions reflecting curatorial guidance through the subject matter which now include content in the form of images, audio and visual effects, and interactive exhibits. Museum creation begins with a museum plan, created through a museum planning process. The process involves identifying the museum's vision and the resources, organization and experiences needed to realize this vision. A feasibility study, analysis of comparable facilities, and an interpretive plan are all developed as part of the museum planning process.

Some museum experiences have very few or no artifacts and do not necessarily call themselves museums, and their mission reflects this; the Griffith Observatory in Los Angeles and the National Constitution Center in Philadelphia, being notable examples where there are few artifacts, but strong, memorable stories are told or information is interpreted. In contrast, the United States Holocaust Memorial Museum in Washington, D.C. uses many artifacts in their memorable exhibitions.

Museums are laid out in a specific way for a specific reason and each person who enters the doors of a museum will see its collection completely differently to the person behind them- this is what makes museums fascinating because they are represented differently to each individual.

Financial uses

In recent years, some cities have turned to museums as an avenue for economic development or rejuvenation. This is particularly true in the case of postindustrial cities. Examples of museums fulfilling these economic roles exist around the world. For example, the spectacular ''Guggenheim Bilbao'' was built in Bilbao, Spain in a move by the Basque regional government to revitalize the dilapidated old port area of that city. The Basque government agreed to pay $100 million for the construction of the museum, a price tag that caused many Bilbaoans to protest against the project. Nonetheless, the gamble has appeared to pay off financially for the city, with over 1.1 million people visiting the museum in 2015. Key to this is the large demographic of foreign visitors to the museum, with 63% of the visitors residing outside of Spain and thus feeding foreign investment straight into Bilbao. A similar project to that undertaken in Bilbao was also built on the disused shipyards of Belfast, Northern Ireland. ''Titanic Belfast'' was built for the same price as the ''Guggenheim Bilbao'' (and which was incidentally built by the same architect, Frank Gehry) in time for the 100th anniversary of the Belfast-built ship's maiden voyage in 2012. Initially expecting modest visitor numbers of 425,000 annually, first year visitor numbers reached over 800,000, with almost 60% coming from outside Northern Ireland. In the United States, similar projects include the 81, 000 square foot ''Taubman Museum of Art'' in Roanoke, Virginia and ''The Broad Museum'' in Los Angeles.

Museums being used as a cultural economic driver by city and local governments has proven to be controversial among museum activists and local populations alike. Public protests have occurred in numerous cities which have tried to employ museums in this way. While most subside if a museum is successful, as happened in Bilbao, others continue especially if a museum struggles to attract visitors. The ''Taubman Museum of Art'' is an example of a museum which cost a lot (eventually $66 million) but attained little success, and continues to have a low endowment for its size. Some museum activists also see this method of museum use as a deeply flawed model for such institutions. Steven Conn, one such museum proponent, believes that "to ask museums to solve our political and economic problems is to set them up for inevitable failure and to set us (the visitor) up for inevitable disappointment."

Funding

Museums are facing funding shortages. Funding for museums comes from four major categories, and as of 2009 the breakdown for the United States is as follows: Government support (at all levels) 24.4%, private (charitable) giving 36.5%, earned income 27.6%, and investment income 11.5%. Government funding from the National Endowment for the Arts, the largest museum funder in the United States, decreased by 19.586 million between 2011 and 2015, adjusted for inflation. The average spent per visitor in an art museum in 2016 was $8 between admissions, store and restaurant, where the average expense per visitor was $55. Corporations, which fall into the private giving category, can be a good source of funding to make up the funding gap. The amount corporations currently give to museums accounts for just 5% of total funding. Corporate giving to the arts, however, was set to increase by 3.3% in 2017.

Exhibition design

Most mid-size and large museums employ exhibit design staff for graphic and environmental design projects, including exhibitions. In addition to traditional 2-D and 3-D designers and architects, these staff departments may include audio-visual specialists, software designers, audience research, evaluation specialists, writers, editors, and preparators or art handlers. These staff specialists may also be charged with supervising contract design or production services. The exhibit design process builds on the interpretive plan for an exhibit, determining the most effective, engaging and appropriate methods of communicating a message or telling a story. The process will often mirror the architectural process or schedule, moving from conceptual plan, through schematic design, design development, contract document, fabrication, and installation. Museums of all sizes may also contract the outside services of exhibit fabrication businesses.

Some museum scholars have even begun to question whether museums truly need artifacts at all. Historian Steven Conn provocatively asks this question, suggesting that there are fewer objects in ''all'' museums now, as they have been progressively replaced by interactive technology. As educational programming has grown in museums, mass collections of objects have receded in importance. This is not necessarily a negative development. Dorothy Canfield Fisher observed that the reduction in objects has pushed museums to grow from institutions that artlessly showcased their many artifacts (in the style of early cabinets of curiosity) to instead "thinning out" the objects presented "for a general view of any given subject or period, and to put the rest away in archive-storage-rooms, where they could be consulted by students, the only people who really needed to see them". This phenomenon of disappearing objects is especially present in science museums like the Museum of Science and Industry in Chicago, which have a high visitorship of school-aged children who may benefit more from hands-on interactive technology than reading a label beside an artifact.

Types

There is no definitive standard as to the set types of museums. Additionally, the museum landscape has become so varied, that it may not be sufficient to use traditional categories to comprehend fully the vast variety existing throughout the world. However, it may be useful to categorize museums in different ways under multiple perspectives. Museums can vary based on size, from large institutions, to very small institutions focusing on specific subjects, such as a specific location, a notable person, or a given period of time. Museums also can be based on the main source of funding: central or federal government, provinces, regions, universities; towns and communities; other subsidised; nonsubsidised and private.

It may sometimes be useful to distinguish between diachronic museums - those that interpret the way in which its subject matter has developed and evolved through time (examples: Lower East Side Tenement Museum and Diachronic Museum of Larissa), and synchronic museums - those that interpret the way in which its subject matter exists at one point in time (examples: The Anne Frank House and Colonial Williamsburg). According to University of Florida's Professor Eric Kilgerman, "While a museum in which a particular narrative unfolds within its halls is diachronic, those museums that limit their space to a single experience are called synchronic."

In her book ''Civilizing the Museum'', author Elaine Heumann Gurian proposes that there are five categories of museums based on intention not content: object centered, narrative, client centered, community centered, and national.

Museums can also be categorized into major groups by the type of collections they display, to include: fine arts, applied arts, craft, archaeology, anthropology and ethnology, biography, history, cultural history, science, technology, children's museums, natural history, botanical and zoological gardens. Within these categories, many museums specialize further, e.g. museums of modern art, folk art, local history, military history, aviation history, philately, agriculture, or geology. The size of a museum's collection typically determines the museum's size, whereas its collection reflects the type of museum it is. Many museums normally display a "permanent collection" of important selected objects in its area of specialization, and may periodically display "special collections" on a temporary basis.

Legal framework of museums

Public vs. private museums

Private museums are organized by individuals and managed by a board and museum officers, but public museums are created and managed by federal, state, or local governments. A government can charter a museum through legislative action but the museum can still be private as it is not part of the government. The distinction regulates the ownership and legal accountability for the care of the collections.

Non-profit vs. for-profit museums

Nonprofit means that an organization is classified as a charitable corporation and is exempt from paying most taxes and the money the organization earns is invested in the organization itself. Money made by a private, for-profit museum is paid to the museum's owners or shareholders.

The nonprofit museum has a fiduciary responsibility in regards to the public, in essence the museum holds its collections and administers it for the benefit of the public. Collections of for-profit museums are legally corporate assets the museum administers for the benefit of the owners or shareholders.

Museums run by trusts vs. corporations

A trust is a legal instrument where trustees manage the trust's assets for the benefit of the museum following the specific wishes of the donor. This provides tax benefits for the donor, and also allows the donor to have control over how assets are distributed.

Corporations are legal entities and may acquire property in a way similar to how an individual can own property. Museums under incorporation are usually organized by a community or group of individuals. While a board of director's loyalty is to the corporation, a board of trustee's loyalty has to be loyal to the intention of the trust. The ramification is that a trust is far less flexible than a corporation.

Current challenges facing museums

Decolonization of museums

During the beginning of the 21st century, a growing global movement for the decolonization of museums has arisen. Proponent
