With about 200,000 entries, StarBriefs Plus represents the most comprehensive and accurately validated collection of abbreviations, acronyms, contractions and symbols within astronomy, related space sciences and other related fields. As such, this invaluable reference source (and its companion volume, StarGuides Plus) should be on the reference shelf of every library, organization or individual with any interest in these areas. Besides astronomy and associated space sciences, related fields such as aeronautics, aeronomy, astronautics, atmospheric sciences, chemistry, communications, computer sciences, data processing, education, electronics, engineering, energetics, environment, geodesy, geophysics, information handling, management, mathematics, meteorology, optics, physics, remote sensing, and so on, are also covered when justified. Terms in common use and/or of general interest have also been included where appropriate.

This compilation probably looks like one of the craziest things a human being could spend his or her time on. Yet nobody would wonder at someone taking a short walk every day - after twenty five years that person would have covered a surprisingly long distance. This is exactly the story behind this list, which appeared first as a few pages within the directory StarGuides (or whatever name it had at that time) and as a distinct sister publication since 1990. The idea behind this dictionary is to offer astronomers and related space scientists practical assistance in decoding the numerous abbreviations, acronyms, contractions and symbols which they might encounter in all aspects of the vast range of their professional activities, including traveling. Perhaps it is a bit paradoxical, but if scientists quickly grasp the meaning of an acronym solely in their own specific discipline, they will probably encounter more difficulties when dealing with adjacent fields. It is for this purpose that this dictionary might be most often used. Scientists might also refer to this compilation in order to avoid identifying a project by an acronym which already has too many meanings or confused definitions.

This book offers a unique review of how astronomical information handling (in the broad sense) evolved in the course of the 20th century, and especially during its second half. It will be very useful for researchers, teachers, editors, publishers, librarians, computer scientists, sociologists of science, research planners and strategists, project managers, public-relations officers, plus those in charge of astronomy-related organizations, as well as by students aiming at a career in astronomy or related space science.

The ship has left the Miraflores Locks, let loose from the 'mules' run by the crews of the Panama Canal Commission. She has picked up speed while passing under the Bridge of the Americas which links de facto the Northern and Southern parts of the continent, and has headed resolutely towards the Pacific Ocean waters along the rows of boats of all kinds waiting to cross the Canal in the other direction. Through a layer of tropical clouds, the setting Sun is bleakly illuminating the tall white highrises of Panama City on the port side. It took a full day to cautiously move through the whole system of locks and cuts. Back in the stateroom, I open again a working copy of this book and type down this foreword on the pocket computer. The last chapter was received the day before while speeding through the Caribbean Sea and my main work as Editor is now over. It has been a real pleasure and a great honour to be given the oppor tunity of compiling this book and interacting with the various contributors through the latest technologies while being sometimes in geographically very different places. The quality of the authors, the scope of experiences they cover, the messages they convey make of this book a unique and timely publication. The reader will certainly enjoy as much as I did going through such a variety of well-inspired chapters from so many different horizons.

Strasbourg Astronomical Observatory is quite an interesting place for historians: several changes of nationality between France and Germany, high-profile scientists having been based there, big projects born or installed within its walls, and so on. Most of the documents circulating on the history of the Observatory and on related matters have however been so far poorly referenced, if at all. This made necessary the compilation of a volume such as this one, offering fully-documented historical facts and references on the first decades of the Observatory history, authored by both French and German specialists. The experts contributing to this book have done their best to write in a way understandable to readers not necessarily hyperspecialized in astronomy nor in the details of European history. Several appendices conclude the book: lists of council members and of Observatory scientific personnel, as well as a compendium of the institutional publications until the year 2000.

Vol. 9 is a record of the first joint symposium of the International Astronomical Union and the Union international d'histoire et de philosophie des sciences, held at the University of Hamburg, Aug. 22-24, 1964.
