When can it be said that a library has a books and information policy at its disposition?
The diversity of practices and tools which claim to be a "books and information policy" leads one to question the very nature of this recent dimension in a librarian's activity. The study of the implementation of these policies reveals both the complex character of the process and the challenge which this work in progress represents for the efficiency and legitimacy of the library. The information policy, made up of trial and error, appears to be a critical construction in perpetual renegotiation fighting against standardization and technology. It questions the aims of the work of the library as well as that of the role of the librarian.
