This calculator came to me through the Librarian's Index to the Internet. Simple to use but effective !

Great Circle Calculator - http://www.gb3pi.org.uk/great.html
          A useful site for calculating direct line distances between
          any two points on the globe. Enter the latitude and
          longitude to find the length "as the crow flies" of the great
          circle which arcs between the two locations. Distances are
          given in miles and kilometers.

Is there an online tool (or can someone give the formula) for calculating
the great circle distance between two points on the globe, given lat and
long? There must be a more accurate way than using a globe and a piece of
string...
Or is there a publication that lists major cities of the world and their
great circle distances from each other?
