There is an upcoming deadline of 15 May to apply for grants from tDAR to help you get your data into tDAR.
Awards of up to $7,000 are available for cultural resource management (CRM) firms, public agencies, individual researchers, universities, colleges and other organizations to support the direct cost of contribution of digital archaeological content (e.g. documents, data sets, images, etc.) to tDAR, Digital Antiquity’s international digital repository. Proposals that demonstrate geographical or thematic coherence, a breadth of audience interest, integration of resource management and scientific research across archaeological projects, and those that contribute different types of digital files related to the same archaeological investigations will be considered favorably.
While tDAR is overwhelmingly focused on North American archaeology (by design) there are a few datasets of interest to those who work in Europe and the Mediterranean.
