Access & Use

tDAR supports broadening the access to a wide variety of archaeological data.  Browsing or searching the tDAR repository enables users to identify digital documents, data sets, images, and other kinds of archaeological data for a number of uses, including research, learning, and teaching.  tDAR enables users to download data files while maintaining the confidentiality of legally protected information and the privacy of digital resources on which a researcher is still working. Our intelligent searching tools make it easy to find exactly what you are looking for.  You can search within any or all of the fields containing the rich metadata associated with each record.  General searches also search within the text of each publicly accessible file.  You are also able to narrow your search by resource type, or spatially by using our map tool.  Additionally, our metadata are indexed by major search engines, meaning that your archaeological information can be located by a wide audience.
