Polestars / star books

As for the pole stars, I know of no better source than Mathematical Astronomy Morsels V by Jean Meeus (pages 353 to 363) at http://www.willbell.com/math/MorselsV.htm. He lists the northern and southern pole stars for a period of 200,000 years.

The morsels series is a great series of books on stars
