    New Explanatory Supplement to the Astronomical Almanac published
    From: Paul Hirose
    Date: 2013 Apr 09, 13:16 -0700

    The third edition of the Explanatory Supplement to the Astronomical
    Almanac has just been published. Although an edition with a 2006
    copyright has long been available, it's actually just the 1992
    Explanatory Supplement in paperback. This new edition is a completely
    updated book. It should be the authoritative guide to computing
    astronomical data for the past or future.
    
    In the table of contents I do not see the "Historical Information"
    chapter of the 1992 edition, which describes the British and American
    almanacs back to Maskelyne's of 1767. I hope the information is still there.
