This article uses the results of a thesis to analyse the changing structure of access services to scientific and technical information in French university libraries, and corresponding changes in the role of Inter-Library Loan services. These changes have mainly occurred with the growing integration of electronic resources in collections and an overhaul of the services on offer. Given the specific features of access systems to scientific information and the wide range of users in the various sections of university libraries, we will be attempting a detailed analysis of the situation in the French university network.
