Authors and publishers who publish texts using the Creative Commons license system can make their work available from Google Books, the Google service that aggregates books and publications and makes them available for research and access, in whole or in part, free of charge.
Authors or publishers who are already in the service can join the new possibility, changing their definitions and using this form of identification of «permissions». New users will soon be able to register online and choose one of the many forms of Creative Commons.
For users this means access to more free access content, which can be downloaded and shared, for later use under the terms of the license.
If authorized by the authors, the works made available through this route may even be modified by those who download them and return to the platform, improved, or at least different.
Creative Commons is a licensing system created to facilitate the identification of what the author of a particular digital work is willing to do with it.
For example, others are allowed to copy, distribute, modify, market, etc. Different symbols allow a quick identification of the «limits» imposed by the creator of digital content.
