A list of terms related to the topic of interest is a prerequisite for any information search, whether it is a traditional literature search or a search of the Internet. Appropriate terms are usually necessary because topical indexes can be very literal. This requirement could lead to a failed search, if relevant information is indexed by terms different from those used by the searcher. Below is a list of terms relevant to the material discussed in Chapter 11. This list is not exhaustive; rather, it is a starting point that can help you choose your own search terms.
