This book presents a typological survey of numerals in selected language groups of the world. In view of the chosen languages and the represented types, it is complementary to the volume on Indo-European Numerals published by Jadranka Gvozdanovic with Mouton de Gruyter in 1992. The invited chapters of the new volume focus on new areas of numeral research, from cognitive, mathematical, historical and typological points of view, opening new vistas on numeral change as well.
