“The Archaeology Data Service supports research, learning and teaching with freely available, high quality and dependable digital resources. It does this by preserving digital data in the long term, and by promoting and disseminating a broad range of data in archaeology.” To support this goal, the ADS allows access to hundreds of thousands of documents, ranging from archaeological journals to books/monographs to unpublished field reports. Its Archsearch feature aggregates material from a wide variety of sources such as the Historic England National Inventory, various archaeological trusts, and the Council for British Archaeology. A great site!
