						Definition of categories and sub-categories
			
				
					|  | 1. | Structures |  
					|  | Artifacts originally created to define space for human activities or to be used as components of space-defining artifacts. |  
			
				| • | Building |  
				|  |  |  
				|  | An artifact originally created primarily to provide or define a  space with a controllable climate, usually through enclosure, for  human activities. This sub-category may include permanent  structures, such as garages or office buildings, or portable  structures, such as tents. It includes most human-made structures.  Houses, barns, warehouses, train stations, and jails are all  primarily intended to provide spaces that can be kept warm or  cool and dry. Architectural samples integral to buildings, such as  wall sections or roof sections, should be catalogued in this sub-category  as parts of buildings. Separable, distinct, and interchangeable components, such as doorknobs or window sashes, should be classified as "Building Components". |  
				|  |  |  
				| • | Building Component |  
				|  |  |  
				|  | An artifact originally created as a separate, distinct, and generally  interchangeable structural or decorative part of a building (though  such artifacts as hinges, for example, can be used on non-building  artifacts such as gates or tables). Though building components are  distinct objects, they function as parts of larger structures rather  than as independent units. This sub-category includes such objects  as mantels and window frames, but excludes parts of buildings or  other structures that lack distinctiveness or interchangeability,  such as roofs, chimneys, or joists. Also excluded from this sub-category  are parts of buildings that are not integral parts of a structure, such as furnishings, lighting devices, and plumbing fixtures, all of which are listed in the "Furnishings" category. |  
				|  |  |  
				| • | Site Feature |  
				|  |  |  
				|  | An artifact originally created as a distinct element that is  associated with a site, a building, or other structure. Rather than  functioning simply as a part of a larger structure, a site feature is  an independent entity that complements other structures. This sub-category includes such objects as birdbaths, flagpoles, gates, and fences. |  
				|  |  |  
				| • | Other Structure |  
				|  | An artifact originally created primarily to modify the environment  or landscape or to define a space for some reason besides climate  control. This sub-category includes dams, mines, and bridges.  Structures such as sports complexes that are primarily intended to  provide controlled access and convenient seating should be placed  in this sub-category. Some other structures may have climate-controlled  spaces, such as the space under a dome in a stadium or the generating room of a hydro-electric dam, but these spaces serve a secondary role to the function of the structures. |  
			
				
					|  | 2. | Furnishings |  
					|  | Artifacts originally created to facilitate human activity and to  meet physical needs of people generally by offering comfort,  convenience, or protection. Clothing is excluded from this  category as it addresses only the needs of specific individuals.  Furnishings are not artifacts used as active agents in other processes such as tools or equipment; they passively enable human activity. |
