Book Description
Since its founding in 1839, the Harvard College Observatory has pioneered in the development of modern astronomy. Its first directors early recognized the potential of spectroscopy in revealing the constitution of the stars, and of photography in determining the positions and motions of celestial objects; the library of photographic plates made under their direction provides an invaluable history of the stellar universe for the period. The Observatory also pioneered in using the talents of women, several of whom became noted astronomers, and their monumental classification of stars from spectral records constitutes a fundamental contribution to astronomical knowledge. The authors vividly portray the genesis, growth, and achievements of a major scientific institution and its relations with other observatories. Through the use of photographs and correspondence they also portray the men and women who played essential roles in the development of astronomy in the nineteenth and early twentieth centuries.

Book Description
Founded in 1911, the AAVSO boasts over 1200 members and observers and is the world's largest non-profit organization dedicated to variable star observation. This timely book marks the AAVSO's centennial year, presenting an authoritative and accurate history of this important association. Writing in an engaging and accessible style, the authors move chronologically through five eras of the AAVSO, discussing the evolution of its structure and purpose. Throughout the text, the main focus is on the thousands of individuals whose contributions have made the AAVSO's progress possible. Describing a century of interaction between amateur and professional astronomers, the authors celebrate the collaborative relationships that have existed over the years. As the definitive history of the first hundred years of the AAVSO, this text has broad appeal and will be of interest to amateur and professional astronomers, as well as historians and sociologists of science in general.

Book Description
Observing variable stars is one of the major contributions amateur astronomers make to science. There are 36,000 variable stars listed in the General Catalogue of Variable Stars, so it is clearly impossible for the limited number of professional observatories to target even the majority of them. That's where amateur astronomers come in - thousands of them turning their telescopes to the sky every night. Variable star observing is the most popular of "real science" activities for amateurs, and Gerry Good's book provides everything needed. The first part of the book provides a highly detailed account of the various classes of variable star, with examples, illustrations and physical descriptions. The second section covers practical aspects of observing, everything from preparation and planning, through observing techniques, to data management and reduction.
