"preferred" following a term indicates that the term is the so-called "preferred term" for the record. It is typically the first in a list of terms in the record.
A preferred term or "descriptor" is flagged in order to provide a default term for the thesaurus and other displays. It may also be used by cataloguers who wish to apply AAT-Taiwan as an "authority," and consistently use a single term to refer to a concept. In AAT-Taiwan, the "preferred" term is the commonly used term in Chinese(Traditional). American English and other languages may also be flagged. For example, the preferred Chinese(Traditional) spelling will be marked with a "P", as in "Chinese(Traditional)-P."
Diacritics: If a box displays instead of a character in a name or term, this means that your system cannot display the Unicode character represented. You may view the full name or term with correct diacritics by using Vista, Mac OS 10.5, or often by pasting the word into an MS Word document.
