From a national legislative perspective, there are various academic treaties on matters relating to copyright and neighboring rights. Over the years there have also been a number of books, publications and papers published on the important subject of collective management of copyrights and neighboring rights. WIPO has, in addition to its extensive contribution to the international copyright and neighboring rights fields, commissioned experts to write material to be used in conjunction with various Collective Management training activities. To enhance practical materials available to interested parties, WIPO has engaged the writers to further produce and compile two tool kits, in co-operation with a number of non-governmental organizations (NGOs) representing collective management organizations (CMOs) in the fields of copyright in musical and audio-visual works and neighboring rights in sound recordings. The contribution and assistance of the NGOs and other experts has been valuable and the writers’ appreciation is extended to them all.
