How has the information been collected?

The Devon HER was started in 1975 by the Devon Committee for Rescue Archaeology and was transferred to Devon County Council in 1979.

The HER has information taken from published archaeological and historic sources, as well as acting as a repository for otherwise unpublished sources. Information has been collected from both primary and secondary sources: original documents, historic maps, learned society journals, antiquarian observations and excavations, aerial photographs and modern archaeological fieldwork.
