The University of Connecticut Libraries recommend use of the Agreement to Extend Author Rights, which originated at MIT and has been adapted by the Boston Library Consortium for member institutions. The amendment gives authors and their institutions the right to use the authors' scholarly work in educational and research-related ways in either print or digital format.
