This year we begin the transition that will take Digital Antiquity and tDAR from a grant-supported financial model to user-supported, not for profit entity.  Beginning this week all uploads to tDAR carry a modest, one-time fee to ensure the long-term preservation of records archived in the repository. 



Item Cost per File
1-9 Files $50
10-49 Files $40
50-99 Files $30
100-499 Files $25
500-999 Files $20
1,000-4,999 Files $15
5,000-9,999 Files $5

* All files come with 10 MB of space


Our price structure is based on a sliding scale starting at $50 for 1 file of up to 10 MB.  Storage space is not allocated per file, but “pooled” among all your files.  Additional space can be purchased as needed for large files (like large data sets, images, or 3D scans) by contacting our office. We accept MasterCard, Visa, and American Express via our secure online forms. For purchase orders please contact our office to set up an online billing account.  Detailed information on pricing, along with examples and a simple calculator can be found on our website at

If you have already contributed files to tDAR, know that all of the records you have created and files you have uploaded will remain in tDAR as before.  You may continue to access the records, download files, and edit the metadata.   Browsing, searching, and downloading content from the wealth of archaeological information archived in tDAR will remain a free service. 

We thank you for your support of tDAR and look forward to continuing to serve you in preserving and providing access to archaeological information long into the future. 

If you have any questions, we’re happy to talk with you about the changes.  Call or email (480) 965-1369;
