The collection of terms in this thesaurus has been designed to permit clear indexing and classification of records in the Seattle City Clerk's office, but it is of limited scope. Subjects dealt with most completely are those having to do with the main activities of City government. For example, public works, transportation, and housing are each a main focus of City activities, so there are many terms present to permit specific indexing. Geographical concepts are also an emphasis; terms are included for most Seattle neighborhoods and for major geographic features. Topics which are included in only the briefest way (i.e. few terms) are those which only indirectly relate to Seattle City government's activities.
