Some information sources are older and may be out of date on particular subjects. If you are planning on traveling or working in a different country, please consult multiple sources and be on the lookout for more current information. However, if you have time to read up on the history of your destination country, your hosts will likely be impressed by your efforts.
Going Global covers a selection of countries and includes culture guides with info on subjects such as local customs, greetings, language, business culture, and how women are treated. Look for the Cultural Advice section at the bottom of each Country Guide.
