This volume presents a selection of papers from the «3rd International Conference on Non-Dominant Varieties of Pluricentric Languages» that was held in 2014 at the University of Surrey, Guildford (UK). The papers in section one deal with the theoretical aspects of pluricentricity and methods of description of the variations in pluricentric languages. Section two contains a number of papers about «new» pluricentric languages and «new» non-dominant varieties that have not been described before. Section three showcases pluricentric languages that are used alongside indigenous languages and section four deals with the pluricentricity of special languages.
