There are many types of museums, from very large collections in major cities, covering many of the categories below, to very small museums covering either a particular location in a general way, or a particular subject, such an individual notable person. Categories include: Fine Arts, Applied Arts, Craft, Archaeology, Anthropology and Ethnology, History, Cultural History, Military History, Science, Technology, Children’s Museums, Natural History, Numismatics, Botanical and Zoological Gardens and Philately.
Within these categories many museums specialize further, e.g. museums of modern art, local history, aviation history, agricultural or geology. A museum normally house a core collection of important selected objects in its field. Objects are formally accessioned by being registered in the museum’s collection with an artefact number and details recorded about their provenance. The persons in charge of the collection and of the exhibits are known as curators.
