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
In the Victorian era – or for non-British readers, the mid-to-late nineteenth century – amateur astronomy tended to center on Solar System objects. The Moon and planets, as well as bright comets, were the key objects of interest. The brighter variable stars were monitored, but photography was in its infancy and digital imaging lay a century in the future. Today, at the start of the twenty-first century, amateurs are better equipped than any professionals of the mid-twentieth century, let alone the nineteenth. An amateur equipped with a 30-cm telescope and a CCD camera can easily image objects below magnitude 20 and, from very dark sites, 22 or 23. Such limits would have been within the realm of the 100- and 200-inch reflectors on Mount Wilson and Mount Palomar in the 1950s, but no other observatories. However, even those telescopes took hours to reach such limits, and then the photographic plates had to be developed, fixed, and examined by eye. In the modern era digital images can be obtained in minutes and analyzed ‘on the fly’ while more images are being downloaded. Developments can be e-mailed to other interested amateurs in real time, during an observing session, so that when a cataclysmic event takes place amateurs worldwide know about it. As recently as the 1980s, even professional astronomers could only dream of such instantaneous communication and proc- sing ability.

Book Description
As automation and competitiveness between companies and countries grows, the need for the speedy research and delivery of information is becoming greater than ever before. Defining technology transfer as ‘the process of getting technical knowledge, ideas, services, inventions, and products from their origin to wherever they can be put to practical use’, this book, first published in 1991, explores the role of the information specialist in the technology transfer process. It brings together discussions from information mediaries associated with federal information centres, academic research institutions, and a large metropolitan public library. Agencies and organizations at the federal, state, and local level that are involved in and responsible for technology transfer programs are described in a who's who section of the volume, and the system for the distribution of information at NASA is covered in detail, this being considered by some to be the birthplace of the technology transfer concept. The various regional NASA Industrial Application Centers are also identified, and the numerous print and online services available are noted as well. Other topics covered include the use of technology transfer in agricultural programs to improve U.S. competitiveness in the global marketplace and how the large public library can promote technology transfer by acting as important centres for information transfer and research.
