Subjects Form (Index Terms Look-up Tool)
You can access the Index Terms Look-up Tool by clicking the Index Terms link on the Basic or Advanced Search Form.
Selecting subject terms
The subject term search is the default option on the Subject Tab already selected from the drop-down. To search for subject terms, you may browse the alphabetical list by scrolling, browse the subject term hierarchy, or search the alphabetical list using the Find a term feature.
To browse the alphabetical list, click a letter to find terms that begin with this letter, and scroll. These lists can be very long, so alternatively you may want to use your browser’s Find feature to look for a term.
To browse the hierarchical list, click Hierarchy to display the subject terms organized by category. Expand the broader terms to browse narrower terms, and collapse the narrower terms to display only broader terms.
To use the Find a term feature to search terms in the alphabetical list, use the default "containing" search or select the “starting with” option from the drop-down, enter a term in the search box and click the Find button.
Note:The search is not case-sensitive.
Once you decide on the term or terms you would like to use in your search, select the box that is adjacent to the term, and click OK - Paste to Search to insert the index term you have selected into the search form.
Note:If you make multiple selections, the pasted sources will be separated from each other by the logical connector "OR". You may select as many items as you want; however, note that if you perform a second search or try to navigate to another part of the index before you paste the terms to search, your selections will be lost.
Selecting geographical terms
to access the geographical terms list, select Geographical Terms from the Select type drop-down list. Browse the alphabetical list or use the Find a term feature to search for cities, states, counties, countries, and continents. Terms may be selected and inserted in the search following the same instructions that work for non-geographical subject terms.
