If your astrology software is Astrolog32, here you may download the newest compressed atlas files(.atl) for the whole world and the US at once (i.e. no need to download one file for each city separately again). The compressed files in zip format contains longitude and latitude data for many many cities.

From my experience, there are more places than Astrodienst.com.
Useful for anyone who does many charts for many places.
