Absolutely terrific article in the new Issues in Science & Technology Librarianship by Ibironke Lawal called "Scholarly Communication: The Use and Non-Use of E-Print Archives for the Dissemination of Scientific Information." It uses a very well done survey to explore the scholarly communication patterns of various disciplines with respect to e-prints. As expected, physics & astronomy come out on top and just as interestingly, chemistry comes out on bottom. This article brings together in a concrete way a lot of the threads running throught the science librarian community these days about free online scholarship, the Web and the role of institutional repositories versus discipline-based resources. Highly recommended.
