A museum is distinguished by a collection of often unique objects that forms the core of its activities for exhibitions, education, research, etc. This differentiates it from an archive or library, where the contents may be more paper-based, replaceable and less exhibition oriented, or a private collection of art formed by an individual, family or institution that may grant no public access. A museum normally has a collecting policy for new acquisitions, so only objects in certain categories and of a certain quality are accepted into the collection. The process by which an object is formally included in the collection is called accessioning and each object is given a unique accession number.

Museum collections, and archives in general, are normally catalogued in a collection catalogue, traditionally in a card index, but nowadays in a computerized database. Transferring collection catalogues onto computer-based media is a major undertaking for most museums. All new acquisitions are normally catalogued on a computer in modern museums, but there is typically a backlog of old catalogue entries to be computerized as time and funding allows.

A veduta (Italian for 'view'; pl. vedute) is a highly detailed, usually large-scale painting or, more often, print of a cityscape or some other vista. The painters of vedute are referred to as vedutisti.

Collections management involves the development, storage, and preservation of cultural property, as well as objects of contemporary culture (including contemporary art, literature, technology, and documents) in museums, libraries, archives and private collections. The primary goal of collections management is to meet the needs of the individual collector or collecting institution's mission statement, while also ensuring the long-term safety and sustainability of the cultural objects within the collector's care. Collections management, which consists primarily of the administrative responsibilities associated with collection development, is closely related to collections care, which is the physical preservation of cultural heritage. The professionals most influenced by collections management include collection managers, registrars, and archivists.

William Thompson Walters (May 23, 1820 – November 22, 1894) was an American businessman and art collector, whose collection formed the basis of the Walters Art Museum.

Special interests are highly focused interests common in autistic people. They are more intense than typical interests, such as hobbies, and may take up much of a person's free time. A person with a special interest will often hyperfocus on their special interest for hours, want to learn as much as possible on the topic, collect related items, and incorporate their special interest into play and art.Some interests are more likely to be seen as special interests if they are particularly unusual, specific, or niche. Autism rights advocates and psychologists say this binary of acceptable "passions" and pathologised "obsessions" is unfair. Terms like circumscribed interests, obsessions, or restricted interests have historically been used to describe special interests, but these terms are discouraged by autism rights advocates.

Special interests are sometimes confused with hyperfixations. Hyperfixations are typically short-lived periods of strong interest in a subject over a few days to months which are especially common in people with attention deficit hyperactivity disorder, while special interests are most common among autistic people and last for longer periods of time, typically years.
