Reprint edition. Errata sheet loosely inserted. A fine set.

Luther's compilation is an exhaustive new bibliography on the literature of astronomy. It records over 4000 authors and 15,000 titles, with an additional 3,000 new cross-references. Most authors are recorded with full names, dates of birth and death, and the authorities for that information. Most titles are recorded with the approximate size of the book, place of publication, and date of publication. Special care has been taken to record titles by obscure minor figures, meteorological titles, and unconventional titles. The inclusion of serial off-prints gives a breadth to the listings of each other which has yet to be approached by the offerings of on-line catalogues. The work has been compiled with the attention to detail and has taken several years to complete. For the first time the holdings of the Royal Astronomical Society have been brought up to date and augmented for the student of the historical literature of astronomy.
