This thesaurus consists of a list of “preferred terms” and “non-preferred terms” each with an indication of the keyword(s) to be used in indexing. It will also show relations between terms: “broader terms” (BTs), “narrower terms” (NTs) and “related terms” (RTs). Many terms will include “scope notes” (SNs) clarifying their intended use (the subject areas that they cover). Below is a list of the different types of entries that appear in the thesaurus:

SC           “subject category” - broad subject area (processes, materials, applications, etc.)
SN          “scope note” - explaining the meaning of a term
USE        points from non-preferred term to preferred term
UF          “used for” - the opposite of USE
UA          “use and” - for cases where a concept is expressed by two keywords used together
UFA       “used for (and)” - the opposite of UA
NT          “narrower term” - the opposite of BT
BT           “broader term” - generic-specific, part-whole, etc.
RT           “related term” - similar terms, terms in same subject area, opposites
HIS         “history” - date added, term(s) used before that date
Please note that British English is used in this Thesaurus. There is a list of American spellings and terminology and their British equivalents.
