Post a notice clearly and prominently on your website.
Here are some sample texts:
- I have made these materials accessible for purposes of education, commentary, and research. I respect the rights of copyright holders. Upon request, I will remove material from public view while we address a rights issue. If you have questions about your own materials, please contact me...
