The Global Network Navigator/Koblas Currency Converter

This service is part of O'Reilly's (a major computer book publisher) Global Network Navigator. With it, one can check a number of exchange rates that are updated weekly. In a neat twist, one can easily calculate one currency relative to any other currency.

Daily exchange rates, for a smaller number of exchange rates and in a slightly less useful format, can be found at the EBB. In addition, I understand that Holt's Market Report carries exchange rates.
