Subject Headings
Using subject headings (2)
In viewing some of the records retrieved with this search, you might also find that there are interesting combinations of subjects. For instance, you might find a record that combines two topics you find interesting, human engineering and aeronautics.
You can then take both of these terms, “Human engineering” and “Aeronautics,” and enter them in a subject keyword search joined with the word “and.” This search will retrieve all of the Library’s records with both of these terms in their subject headings, providing you with most, if not all, of the Library’s materials on this combined topic. (Note: The "Advanced Search" feature is being used here to take advantage of the larger search box to display the whole search phrase.)
