Evolution of this book
The FTA has reused existing course materials from the Universitat Oberta de Catalunya (UOC). The first version of this course book was published in 2004 for the Master Programme in Free software of the UOC. In 2008, this book was translated into English with the help of the SELF (Science, Education and Learning in Freedom) Project, supported by the European Commission's Sixth Framework Programme. In 2009, this material has been improved by the Free Technology Academy. Additionally the FTA has developed a study guide and learning activities which are available for learners enrolled in the FTA Campus.
