The purpose of this Gazetteer and Atlas of Astronomy (GAA) is to list, define and illustrate, for the first time, every named (as opposed to merely catalogued) object in the sky within a single reference work for use by the general reader, writers and editors dealing with astronomical themes, and those astronomers concerned with any aspect of astronomical nomenclature. Each part of the GAA will contain: • An introduction to the nomenclature of the body or group of bodies in question • A glossary of terminology used • A gazetteer listing in strict alphanumerical sequence essential information defining the body or feature concerned • An alphanumerically arranged classified index of all the headwords in the gazetteer • An atlas comprising maps and images with coordinate grids and labels identifying features listed in the gazetteer • Appendix material on the IAU nomenclature system and the transcription systems used for non-roman alphabets
