The database for the Louvre’s collections consists of entries for more than 480,000 works of art that are part of the national collections and registered in the inventories of the museum’s eight curatorial departments (Near Eastern Antiquities; Egyptian Antiquities; Greek, Etruscan and Roman Antiquities; Islamic Art; Paintings; Medieval, Renaissance and Modern Sculpture; Prints and Drawings; Medieval, Renaissance and Modern Decorative Arts), those of the History of the Louvre department, or the inventories of the Musée National Eugène-Delacroix, administratively attached to the Louvre since 2004.
The Collections database also includes so-called ‘MNR’ works (Musées Nationaux Récupération, or National Museums Recovery), recovered after WWII, retrieved by the Office des Biens et Intérêts Privés and pending return to the legitimate owners. A list of all MNR works conserved at the Musée du Louvre is available in a dedicated album and may also be consulted in the French Ministry of Culture's Rose Valland database.
Lastly, the Louvre Collections database includes information on works on long-term loan from other French or foreign institutions such as the Bibliothèque Nationale de France, the Musée des Arts Décoratifs, the Petit Palais, the Fonds National d'Art Contemporain, the British Museum and the archaeological museum of Heraklion.
Works are presented in the Collections database regardless of where they are currently located: on display in the Musée du Louvre or Musée Delacroix, visible in the gardens, on long-term loan in France or abroad, in storage, etc. Information about their location is included in each entry.
The entries in the Collections database, updated daily based on input from management and documentation services, are written by a team of experts from the Louvre, notably curators, research, documentation and management services from each of the eight curatorial departments and the Musée Delacroix, the History of the Louvre department, the gardens subdepartment, and the acquisitions and preventive conservation divisions. The Research and Collections Department oversees the operational and scientific coordination of the database, with support from IT staff.
The majority of entries include photographs taken during campaigns organised by the Musée du Louvre mostly in association with photographers from the Réunion des Musées Nationaux-Grand Palais and photographers with contractual agreements with the Musée du Louvre.
The Louvre’s collections site offers several research tools: full-text search engine; advanced search form; features that filter search results according to date of creation, collection the work belongs to, where the work is located, category of work, artist/maker; themed albums; and an interactive map to find works on display in the museum. Search results can also be exported as a flat file (CSV). Each entry has its own URL based on the ARK identification protocol to guarantee uniqueness and durability. The permalink is located at the bottom of each entry. The site allows users to download texts about the artwork in JSON format.
