The Medical Library operates in a dual context, the academic and the health-care one; it must therefore provide a range of services. Thus the biomedical librarian must adapt and acquire new skills and thus new professional profiles have to be identified. The new definition of the Medical Library should be ‘integrated’, no more physical or virtual space reserved only to students and researchers from the academic world but multifunctional reference able to offer its services to all health users, a library whose social role must go far beyond the structural context in which it appears and become an efficient support infrastructure for scientific research and for transfer of knowledge in clinical practice.
