Bibliographic Information on Electronic Documents

Bibliographic information is added value for primary documents to facilitate the search for information and access to documents. The extension of classic library catalogues, from documentary databases and archival research tools to access to electronic documents can be achieved by a single link. This is offered in the recent addition of a specific field in the marc format. Equally, other approaches are being tested in other communities of users by the introduction of added value information in the electronic document itself using the format of the document. They are contributing to the construction of the libraries and archives of tomorrow.
