I use the CIA factbook frequently
I shared these sites with Jaime earlier, and I think that they fit into this category.

http://www.dialoguecentre.org/, and it is loaded with useful information and links.
I also recommend
http://www.sister-cities.org/, which is the home site to a program that links cities across the world. Chances are that your home city has one or more sister cities in varying countries. They sponsor events and projects that promote global dialogue and understanding. For example, one of Boulder, Colorado's sister cities is in Dushanbe, Tajikistan. One of the projects between these two cities is a traditional Tajiki tea house that was built in Boulder involving over 40 artisans from Tajikistan. They serve a wide variety of international cuisine and of course, tea. The artwork is stunningly beautiful. You can see pictures and learn about the tea house here:
