This unique volume provides a complete reference on variable stars. It presents a wealth of typical light- and colour-curves to allow identification, together with a detailed and up-to-date description of each subclass. The editors, together with seven other world experts, have created a unique pictorial atlas of variable stars. In the first chapter they give a clear introduction to the nomenclature and classification of the light curves of variable stars, and to photometric systems. In the remaining chapters they provide a detailed account of each subclass: from eruptive, pulsating, rotating and cataclysmic variables, through to eclipsing-binary systems and X-ray binaries. Specific variable stars, types and classes of variables, together with key astrophysical terms can be quickly and easily located in the book by means of detailed object-name and subject indexes. This comprehensive and up-to-date volume provides an essential reference for all those interested in variable stars - from

The IAU Centenary Symposium was held at its General Assembly in Vienna in 2018. It starts with plenary lectures, by Malcolm Longair on 100 years of astronomy, astrophysics and cosmology, and by Catherine Cesarsky, who reflects on a century of IAU history. There follows reminiscences from past IAU presidents and general secretaries and presentations on various aspects of IAU history, including some of the famous astronomers who served the Union. The volume then examines the relations between the IAU and different geographical regions, including the issues relating to the Central Powers after World War I, and the 'China crisis', when China withdrew from the Union in 1960 and was absent for two decades. The IAU's internal structures and organization are reviewed, along with trends in astronomical publishing and astronomical education. IAU S349 finishes with a vision of the IAU's future from its current president, Ewine van Dishoeck.
