The 40th Book Festival opened Sunday evening at the Zappeion Mansion in central Athens.
The Festival, currently in its 30th year, is dedicated this year to the 2011 European Year of Volunteering.
The 40th Book Festival, which was inaugurated by Greek President of the Republic Karolos Papoulias, is organised by the Association of Book Publishers in collaboration with the City of Athens' Cultural Organisation.
Some 150 publishers are presenting more than 50,000 books at the Festival, which also includes a pavilion dedicated to books and magazines that were censored or prohibited during the 7-year dictatorship in Greece and a pavilion of the National Transplants Organisation with informational material on organ donation.
Running through September 18, the Festival is open to the public Mondays-Thursdays from 6:00 in the afternoon to 10:30 at night, on Fridays and Saturdays from 6:00 p.m. to 11:00 p.m., and on Sundays from 11:00 a.m. to 10:30 p.m.
