Several things have pushed Grenoble Public Library to begin a programme on the matter of holdings policy. The context is characterized by its own difficulties, linked in particular to the fact that it is part of a very large network, resulting in a large number of people charged with managing collections, but which also brings certain assets. « Directive texts » are not all developed as it would be necessary : the elements exist, and they must be brought together without delay. Despite this, certain actions have been taken : awareness training for collection managers, educative training, projects aimed at the interior functions of establishments or across the network such as committees and work groups. Also evoked are the perspectives on actions foreseen for the near future.
