The Premier recensement des métiers des bibliothèques is the first attempt to define what the members of these professions are doing, which skills they display, and which fields of knowledge are associated with their activities and skills in the French university and research libraries. It gives a better and sounder basis to design the contents and methods of the training programs aimed at the members of these professions. Though it has been conceived within the frame of the university and research libraries, it could and should be extended to cover the needs of the professionals working in other types of libraries, particularly the public libraries. It is also worth checking whether, the list of skills is complete and precise enough to allow the professors in this field to improve the contents and methods of the training programs they are delivering to the future professionals. Suggestions are made to this end. It could become possible to set up a global concept of the training programs of all library professionals in all types of libraries.
