With the creation of its partner centres in 1994, the Bibliothèque nationale de France (BnF) joined a national information research network. This policy has not always been fully understood. The factors which led to this misunderstanding can be identified: inflexibility in the criteria for the attribution of acquisitions' budgets; the neglect of network interoperability; lack of transparency in the financial mechanism. Contributing to the enhancement of research resources, via an updated French collective catalogue (CCFr), remains an objective for the BnF. Other areas of work in hand within the network concern heritage collections.
