First, you must determine which style guide you want to use. If you are publishing, you will use The Chicago Manual of Style. For academic writing, you will use MLA, APA, Turabian, or another style. For news writing, you might use AP style. These style guides will tell you what kind of information to use and how to cite it. They are usually available in the local library. If you just need something generic, simply include all the information needed for a person to find the source. Here are two examples:

"Tunisia." CultureGrams 2005 World Edition. Lindon, Utah: ProQuest Information and Learning, 2004.

OR

"Peru." CultureGrams. Vers. 2005. CultureGrams/ProQuest Information and Learning: Lindon, Utah. 05 Feb. 2005. http://online.culturegrams.com/secure/world/world_country.php?contid=7&wmn=South_America&cid=125&cn=Peru.

Adapt these examples to other CultureGrams products.
