口述歷史
Oral history is the recording of personal memories and histories of those who experienced historical eras or events. Oral history is a method of historical documentation, using interviews with living survivors of the time being investigated. Oral history often touches on topics scarcely touched on by written documents, and by doing so, fills in the gaps of records that make up early historical documents. Oral history preservation is the field that deals with the care and upkeep of oral history materials, whatever format they may be in.
