A number of libraries across Europe collaborate to make this spectacular Europeana online exhibit that "virtually reconstruct[s] the exceptional royal libraries of the Carolingian emperors, Charles V of France, and the Aragonese Kings of Naples." For each of these three libraries, visitors can explore an essay accompanied by digitized images from some of the books held in these libraries. For example, in the Library of Charles V and Family, visitors will find images from the Grandes Chroniques de France, a book that was "especially made for King Charles V, who almost certainly supervised its production." Meanwhile, in the Bibliotheca Carolina section, visitors can examine the Capitulare de Villis, a ninth century manuscript that is "the only surviving written exemplar both of Pope Leo III's letters to Charlemagne and of the famous capitulary (collection of instructions) Capitulare de villis, thought to have been issued by Charlemagne." In addition to the three sections dedicated to the libraries, this exhibit also includes a section that explains medieval bookbinding and book arts.
