Computer Literacy bookstore lists, in its latest New Book Bulletin,
the book

   Calendrical Calculations
   Nachum Dershowitz/Edward Reingold
   Cambridge University Press, 300 pp., $64.95 [!]
   ISBN: 0521564131

   "Describes the following calendars: Gregorian, ISO commercial,
    Julian, Coptic, Ethiopic, Islamic, Persian, Baha'i, Hebrew,
    Mayan, French Revolutionary, Chinese, and both Hindu calendars
    (mean and true). Delves into units and taxonomy, negative years,
    day numbers, cycles and epochs. This is a scholarly dissertation
    that emphasizes that emphasizes computational accuracy, discusses
    and examines algorithms, and defines their relationship to each
    other. Supplementary material and additional information available
    on the associated Web site."

For this kind of ca$h, I guess this book is only for those who are
REALLY serious about their calendars.

If you're thinking about getting this book, Computer Literacy is
having a 20% discount sale off selected books (all the books in the
Fall 1997 New Book Bulletin). For this book, it lowers the price from
$64.95 to $51.96.

The only catch is, you have to either bring the back page of the
Bulletin to one of their stores (only in Northern Virginia and the
S.F. Bay Area), OR you can order from their web site (clbooks.com)
and enter code NBB97FALL in the Referral Code field.

FWIW (about US$13 to some... ;)

P.S. I just checked Amazon.com, and they list $64.95 for the hardback,
     but $22.95 for the paperback. The catch HERE is, the paperback
     is listed as "back ordered," and they expect to ship it in 3 - 5
     weeks, but they don't have a "reprint date" for it.
