College & Research Libraries has released "How Institutionalized Are Model License Use Terms: An Analysis of E-journal License Use Rights Clauses from 2000-2009," a preprint by Kristin R. Eschenfelder et al.
Here's an excerpt:
This paper explored the degree to [which] use terms proposed by model licenses have become institutionalized across different publishers' licenses. It examined model license use terms in four areas: downloading, scholarly sharing, interlibrary loan and electronic reserves. Data collection and analysis involved content analysis of 224 electronic journal licenses spanning 2000-2009. Analysis examined how use terms changed over time, differences between consortia and site license use terms and differences between commercial and non-commercial publisher license use terms. Results suggest that some model license use terms have become institutionalized while others have not.
