The Creative Commons licences

Since the adoption of the OA Policy, 91Â鶹¹ú²ú¾«Æ·×ÔÅÄ released hundreds of its books with an open licence, which are already available in this portal. More will be added over the coming months, including new publications and re-editions of existing works.
Last update:25 January 2024

Most of these published works are offered under specially developed Creative Commons licences that allow any user in the world to download, copy, distribute, translate, re-use, adapt, and build on them free of charge. The majority of UNESCO resources will be licenced under the  licence. The requirements of this licence are:

  1. UNESCO is clearly credited as the owner of the original work, and
  2. derivative works may be distributed only under a licence identical to the licence that governs the original work.

Creative Commons licences are model agreements. They are used to give the public the right to use a work protected by copyright. The fewer restrictions a licence contains, the better the licenced work can be distributed and used.

Some publications of the portal have additional licensing conditions, which are explained below:
