tDAR - the Digital Archaeological Record - is an international digital archive and repository. It houses data about archaeological investigations, research, resources and scholarship, to provide broad access to a wide range of archaeological data.

A key aim of tDAR is the long term preservation of digital archaeological data, as well as providing free, easy access to data for the public and researchers. The repository is designed to "enable researchers to more effectively create knowledge of the human past, and resource managers to better preserve and protect archaeological resources."

Within tDAR, users can search for documents, datasets, images, and GIS files, and make use of data integration tools. It also provides a comprehensive list of guides and resources about accessing, using and uploading to the repository, as well as a useful 'data dictionary' and video tutorials.

tDAR is government by Digital Antiquity - a non-profit, multi-institutional and collaborative organisation. Access the repository at www.tdar.org.
