Please find below a link to an article, first published on BBC News Online on 28 October 2016 about the reappearance of a 15th century manuscript in Italy that has been missing for over 30 years. It is only one of 145 volumes stolen from the Passerini Landi library during repairs in 1985. Seventy-two have been recovered so far, but none have been found for years.

Do we need more drastic measures to prevent the theft of books, maps, manuscripts and other art on paper? On 26 June 2015 internationally renowned experts – librarians, archivists, lawyers, auctioneers and rare book dealers – discussed one of the global problems of the antiquarian book trade in the 21st century: the theft of books, manuscripts and prints from public collections such as, in recent years, the Girolamini Library in Naples, the National Library of Sweden, the Danish Royal Library in Copenhagen and, right now, from the Bibliothèque Nationale de France in Paris. ILAB President Norbert Donhofer was invited to speak at the conference at the British Library, which will be followed up by another international meeting in New York in 2016.
