The Bibliothèque nationale de France has revamped the search engine for its online library, Gallica.

Founded in 1997, the site contains over 120,000 volumes and thousands of image and recordings. In a bid to improve the accessibility of Gallica, the institution selected search software from French vendor Exalead. According to the supplier, the chosen search platform contains semantic functionality and the ability to index unstructured data.

Last year, Bibliothèque nationale de France announced a long term partnership with compatriot IT services suppler Atos Origin, which is help the library to digitise its archive. The library expects to have digitised 1,800 terabytes-worth of documents by 2014.
