Truncation Marks Imply “Or” architect*(?, #, $) yields architect architects architecture architectural

About Subject Headings Subject headings are often assigned by human beings. The words in a subject heading might not appear in the item itself. Items on a similar subject are retrieved together by their subject headings.
