[ROLE AND EVOLUTION OF A SPECIALIZED SCIENCE LIBRARY].

This paper deals with the present position of a specialized scientific library, the increase in the number of such libraries, and their development in conjunction with that of the institutes and laboratories to which they belong. It describes the danger for these libraries of too great expansion and the need to restrict themselves to a well-defined area. The different categories of specialized scientific libraries are reviewed, as well as the role of each of these categories vis-à-vis overburdened university libraries. There is an account of the assistance given [by specialized scientific libraries] to university libraries now and in the near future.
