"eHRAF Archaeology is an online, full-text database with information on prehistory of the world. This database, modeled after eHRAF World Cultures, is unique in that the information is organized into archaeological traditions and the text is numerically subject-indexed according to HRAF's modified Outline of Cultural Materials (OCM). This comprehensive subject retrieval system extends search capability well beyond keyword searching allowing for precise subject retrieval, even in foreign language texts. eHRAF Archaeology is organized by regions and archaeological traditions. Each tradition consists of a general summary and full-text documents including books, journal articles, dissertations, and manuscripts."
"The archaeological database provides researchers and students access to archaeological materials for comparative studies within and across regions. Traditions are selected by random sampling from the Outline of Archaeological Traditions, compiled with the help of a distinguished Board of Advisors. To encourage historical and evolutionary analysis, the traditions prior to and following each tradition will be included in subsequent installments." (From the vendor)
