EHRAF Archaeology is a cross-cultural database containing information on the world's prehistory designed to facilitate comparative archaeological studies. This annually-growing eHRAF database is organized by archaeological traditions. The full-text sources are subject-indexed at the paragraph level. Two thesauri, Outline of the world cultures (OWC), and: Outline of cultural materials (OCM), organize the collections and are included as searchable files.
