All publishers of works of art which are prepared for publication by making copies thereof, must deposit, within one month as from the date of publication, five copies of the work at The Ministry of Information & Culture. Non-depositing of a work of art shall be punishable with a fine not exceeding twenty five pounds, without prejudice to the necessity of depositing the copies. Non-depositing shall not result in prejudicing the copyrights stipulated by this law. These provisions do not apply to works of art published in newspapers and periodicals, unless they were published separately. Article(50) The provisions of this law shall apply to authors holding the nationality of the State and foreign authors whose works of art are published, acted or presented for the first time in the Kingdom of Libya, as well as to the works of art of Libyan authors which are published, acted or presented for the first time in a foreign country. While the works of art of foreign authors which are published for the first time in a foreign country shall not be protected by this law, unless they are protected in the foreign country and that this country provides similar protection for Libyan authors for their published, acted or presented works for the first time in Libya. Article(51) Without prejudice to the provisions of the previous article, the provisions of this law shall apply to the works of art which exist at the time of its application. However, with respect to calculating the period of protection of existing works of art, the calculations must include the period which elapsed from the date of the event which shall be considered as the starting point and until the date of implementing the law.
