5.3 Types of Displays

5.3.2 Permuted Displays (9.3.2)

A permuted or rotated display of the terms lists each term multiple times in the alphabetic sequence of the controlled vocabulary for each of the words in the term. For example, a term such as very high frequency radiation would appear four times -- each entry appearing in its proper place in the alphabetic sequence. The two types of permuted displays are Key Word In Context (or KWIC) and Key Word Out of Context (or KWOC), as shown in the following examples.

Example 147: KWIC Index permuted display

Example 148: KWOC Index permuted display
