NA = not available (i.e., subfield was not identified separately in questionnaire for that year).
a This subfield dropped in 2004.
b This subfield introduced in 2001.
NOTE:  Categories are grouped differently from questionnaire and summary reports in that linguistics, history of science, American studies, and archaeology are included in social science and not in humanities, and public administration is included in social science and not in professional fields.
