The Oxford Dictionary of Astronomy was first published in 1997, containing nearly 4,000 entries written by a team of specialist contributors, both amateur and professional, under my editorship. A heavily revised version of that first edition appeared in 2003 in which the number of entries increased to over 4,000. At the same time the type size was reduced slightly, allowing the material to fit into fewer pages than before. A reprint of that revised edition came out in 2004 incorporating further updates, mostly concerning space missions and observatories.

A second edition was published in September 2007. For this, all entries were reviewed by a team of specialists, mostly different from those who had written the original entries. A new departure in this edition was the inclusion of URLs of websites, notably for various space missions, observatories and various other institutions, and online catalogues. In this 2007 second edition over 160 new entries were added to those in the revised edition of 2004, although some minor entries, particularly for small planetary satellites, have been deleted.

The following additions and corrections apply to the second edition of 2007. The online edition is updated frequently.
