Despite the shaky security situation in Israel, not one of the participants in the upcoming Jerusalem International Book Fair has canceled. The 20th Book Fair will take place during the second week of May in the International Congress Center (Binyanei HaUmah). Some 1,000 book publishers from 50 countries will display over 100,000 titles and multi-media articles at the fair. The exhibition has been held in Jerusalem bi-annually since 1963, and is considered one of the leading book fairs in the world - as is evidenced by the lack of cancellations. Entrance to the public will be free, in commemoration of the 20th edition of the fair.
