N.B.
Legal deposit in South Africa is governed by the Legal Deposit Act No. 54 of 1997.
Legal deposit with libraries does not provide copyright protection. Copyright protection is governed by the SA Copyright Act No. 98 of 1978 (as amended) and is granted automatically once a work is created. Only films need to be registered.
