The opportunity to upload resources for free to tDAR will end on December 31st.  Can you catch up with some of our super-users?  Barbara Stark has uploaded nearly 4,000 archaeological records related to her research in Veracruz, Mexico.  PaleoResearch Institute has contributed over 2,000 paleoenvironmental and archaeobotanic reports.  More than 2,000 files chronicling Dean Snow’s investigations of Paleoindian to Historic archaeology of New York have been made available in tDAR.  William Engelbrecht’s research on Iroquoian Ceramics and the Eaton Site includes over 1,000 reports, journal articles, datasets, photos, and maps.  Check out the extensive archaeological data shared by these and hundreds of other archaeologists in tDAR, then add your own!

  • Plan for obsolete technology.
  • Maintain files in open and preferable formats, and accommodate new industry standards for archaeological information.
  • Store rich descriptive metadata with objects.
