The library of Châtenay-Malabry was established 12 years ago; it provides the pharmacy students, searchers and teachers of Paris-Sud University. It has been enhancing information retrieval and document access services. Due to the cuts in funds, the library has withdrawn a huge number of subcriptions in a two steps operation (1981 and 1983). The criteria choosed for that operation were : the usage frequency of the titles, their cost and availability in another centre in Paris area. Although the interlibrary loan has been developing considerably, one cannot regard it as a heal-all, even when its efficiency is beeing strengtened by the new technologies. An increase of new titles cannot but worsen the situation.
