revised May 2019 For educational purposes

Guide Terms / Node Labels



In

the

AAT,

Guide

Terms

and

node

labels

are

records

created

as

a

hierarchical

level

to

provide

order

and

structure

to

the

thesaurus

by

grouping

narrower

terms

according

to

a

given

logic,

but

where

no

concept

is

appropriate

as

a

broader

context

(e.g.,

<styles,

periods,

and

cultures

by

region>

)



Guide

terms

within

the

AAT

are

designated

in

displays

by

angled

brackets,

as

seen

in

the

example

here



GTs are part of the genus/species hierarchical structure



Their descriptors are not used as indexing terms
