The Mazarine Library's new website went live on 16 December 2013; it is also accessible on laptops, tablets and smart phones. New features include search of the main catalogue from the home page, a diary, a detailed description of the collections, a virtual exhibition module, forms for interlibrary loans (ILL) or registration for visits, export to the message service. It is available in French and English and will soon permit readers' pre-registration online.
