This article provides an outline of the Libyan Antiquities at Risk (LAaR) project, which has developed a reference database and website recording Libyan antiquities that are under threat of being stolen and sold on the illegal art market. Since the Arab Spring in 2011 and the subsequent political instability, the number of antiquities that are trafficked out of Libya has risen sharply. The illustrated reference collection created by LAaR is mainly aimed at customs officials, international agencies, museum curators, the police and cultural heritage sector, to alert them about the likelihood of Libyan provenance of previously unrecorded material of similar appearance to known pieces, and thereby help to prevent the sale of Libyan antiquities on the illegal art market. LAaR is a collaboration between the Society for Libyan Studies and the University of Leicester.
