Ebooks for global, regional, or individual countries, are rich resources for traditional etiquette.
The Global Etiquette Guides give 10-20 pages of information for most countries, including descriptions of "Fundamental Cultural Orientations," such as ways to relate interpersonally, view time, deal with risk, and work with society at large. Specifics are given for greetings, communication styles, gestures, dress, situational protocols, dining and drinking, gifts, and business culture. There are ebook versions for two regions below. The Global Etiquette guides for Asia and Europe are available in print at the library (see Reference Books at EMU Library further down this page).
