My projects and collaborations have produced several kinds of original data sets and archives. I strongly believe in sharing data, references, and ideas as soon as they might be of value, even though some would say there’s a risk of being plagiarized.

All original data here have a Creative Commons Attribution-Non Commercial-Share Alike 4.0 International license, and are designed to be shared and remixed. Please let me know if you publish your analysis of the data so that I can learn from your observations. If you expand or extend your data in some way, please let me know and I’ll help disseminate your work. Please remember to acknowledge some of the core work of the original contributors when you present your new work.
