    For our purpose I think it would be better to make copies of the relevant 
    pages from the Nautical Almanac. The end use is to provide a lookup table to 
    solve workbook problems. So part of the learning experience it to find the 
    data in the actual pages. Does Mystic keep old Almanacs? Who might have out 
    of date books like this?
