    I guess I'll order one from Celstaire twenty some dollars vs $43 at the GPO.
    Another book to be considered is the Astronomical Almanac ($40 at the GPO).
    Although much is Greek to me, there are a few gems in it such as
         a extensive star index with RA, Decl, and proper motions
         a great glossary
         a complete description of time scales  and coordinate systems with
    lots of history
         delta T from 1620 forward
         scattered prose on various topics including algorithms.
    It's certainly not an easy book to understand or use but I've learned a lot
    although it took lots of effort.  If nothing else, I've learned I know very
    little about astronomy or the mathematics associated with it.
