The Mapdawg pages:

	Mapdawg home
	GIS and Geographic Data- focus is on links that take you directly to available (and hopefully free to immediately download) spatial data, ready to use in your GIS package; worldwide in scope.
	GIS Organizations- links to selected organizations involved in the production, use, and development of GIS and related geographic tools and spatial data
	GIS Software- Primarily vendors
	Geography and GIS Resources on the internet- sites with general info on the field
	The Mapdawg Old Map page steps back in time away from the GIS high tech world
	send email to the Mapdawg

Other stuff:

	Search the web using Alta Vista
	In the unlikely event you can't find what you need, search farther with Dogpile
