Tell us how you used AHTUS-X

We request that users tell us about any publications, research reports, or educational materials they have created using the AHTUS data or documentation. In the future, we will create a bibliography containing references to publications, presentations, and works in progress that use AHTUS-X data. We welcome information (including author, title, date, and other standard citation material, such as journal name and volume) about books, educational materials, or papers to satisfy a course requirement that draw upon AHTUS data or documentation. Thanks for your help!
