Legal deposit of ebooks in France and its bearings on cataloguing and the National Bibliography

French law on digital legal deposit covers websites and online content as well as ebooks. It imposes no obligation to produce a bibliography in the traditional form, indexing being sufficient. But despite their innovative characteristics, ebooks are still books, and their bibliographic metadata is closer to that of printed materials than to the indexation of web archives. To set up a complete ebook deposit workflow, the Bibliothèque nationale de France (BnF) benefits from its experience with digital documents and its tradition of legal deposit. This paper aims to present the questions that it faces when dealing with the cataloguing of ebooks and the management of their metadata, and the solutions that are emerging.
