Scholars have frequently used in textual analogies such as 'record', 'source' and 'archive' to refer to material evidence of the past since at least the 19th century. The term 'archaeological record' probably originated this way, possibly via parallel concepts in geology (geologic record) or palaeontology (fossil record).[5] The term was used regularly by V. Gordon Childe in the 1950s,[6] and seems to have entered common parlance thereafter.[5]
