Since the works are protected, we can only use it according to the one allowed LPI. For example, a university professor can not make certain uses of a work in class (if these are not contemplated in the law as permitted exceptions) and, therefore, he must first request permission to the rights holder. This, obviously, hinders the use of the works in academic environments.
For example, the author may authorize the reproduction, distribution and public communication of his works in non-commercial environments, or allow more permissive uses such as commercial uses or the creation of derivative works (translations, etc.).
In any case, the original authors should always be quoted and recognized, as well as providing a link to the original license in case the work is reused or disseminated.
- There are other types of use licenses, which are not free access, with which the providers of databases and / or editorial packages detail users as much as the permitted uses and the limitations of use of licensed works. Therefore, the license allows the client to use the purchased or subscribed work only in the conditions agreed with the corresponding supplier.
