Cultural artifact is a more generic term and should be considered with two words of similar, but narrower, nuance: it can include objects recovered from archaeological sites, i.e. archaeological artifacts, but can also include objects of modern or early-modern society, or social artifacts. For example, in an anthropological context: a 17th-century lathe, a piece of faience, or a television each provides a wealth of information about the time in which they were manufactured and used.
Cultural artifacts, whether ancient or current, have a significance because they offer an insight into: technological processes, economic development and social structure, among other attributes.
primary artifacts: used in production (such as a hammer, a fork, a lamp or a camera);
secondary artifacts: relating to primary artifacts (such as a user-manual for a camera);
tertiary artifacts: representations of secondary artifacts (such as a picture of a user-manual for a camera).
Social artifacts, unlike archaeological artifacts, do not need to have a physical form (for example virtual artifact), nor to be of historical value (items created seconds ago can be classified as social artifacts).
