Preferred Term
"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.
