Carnegie Mellon faculty Web pages and publisher policies were examined to understand self-archiving practice. The breadth of adoption and depth of commitment are not directly correlated within the disciplines. Determining when self-archiving has become a habit is difficult. The opportunity to self-archive far exceeds the practice, and much of what is self-archived is not aligned with publisher policy. Policy appears to influence neither the decision to self-archive nor the article version that is self-archived. Because of the potential legal ramifications, faculty must be convinced that copyright law and publisher policy are important and persuaded to act on that conviction. (Contains 6 tables.)
