Digital antiquity

Digital Antiquity supports access to and preservation of archaeological information through its digital repository tDAR (The Digital Archaeological Record). While based in the United States, tDAR’s scope is international and accepts archaeological materials from all seven continents. Digital Antiquity staff are available for consultation during normal business hours. Digital Antiquity will accept a wide range of digital archaeological data for the tDAR repository. Data and documents contributed to the tDAR repository may include digital files related to a wide range of archaeological investigations and topics, e.g., archives and collections, field studies of various scales and intensities, and historical, methodological, synthetic, or theoretical studies.


Please see the tDAR website for up-to-date information on pricing. In general, tDAR pricing is based on the size (both file size and number of files) as well as complexity of the item. Large and complex projects may benefit from a more direct consultation; please contact Digital Antiquity.
