The main aim of collating advanced sociolinguistic cases is to bring together and produce a systematic study of the experiences in the social, private or public spheres that are the most advanced in the normalisation of Basque. Afterwards, the way will be opened up for spreading the knowledge that has accumulated in these experiences. The intention is to encourage reflection on the keys to the success achieved by these organisations and to spread the perspectives and practices that are new in normalisation experiences, both among agents involved in Basque normalisation as well as those involved in sociolinguistics work and in the university field as well.
