We invite users to contribute new resources to the Darakht-e Danesh Library, but we want to ensure that uploaded works are as usable as possible. To that end, if you are the original creator of your upload (ie. you did not take any ideas or content from anywhere else), we recommend that you use the Creative Commons Attribution 4.0 International License. This license requires that you are credited for your work, but it also allows other people to re-use and adapt the resource for their own teaching.
If you translated the resource you’re uploading from another language, you can still use the Creative Commons Attribution license for your work as a translator. However, translations need to show the licensing of the original work as well as the translation. Thus, if you didn’t create the work you’re translating from yourself, see below.
Works taken from third-party websites, books, or other sources will often not be under the same license as we recommend for original uploads. That’s fine – we just want to make sure that uploads can be re-used and adapted. Thus, we require not that the resource be available for free but rather that it is under a free license. Any license that allows distribution and adaptation is fine; examples of acceptable licenses include Creative Commons Attribution, Attribution-ShareAlike, Attribution-NonCommercial, or Attribution-NonCommercial-ShareAlike (but NOT No Derivatives). Works that are in the public domain (not covered by copyright) can also be used. Please make sure to include a source for your upload, including both the author or publisher and (where relevant) the source URL.
