While not official subject headings, these keywords can be very fruitful for your research. Try to also think of other terms such as these. Keyword searches look at all the information in the book or article record including title, author, abstract, table of contents, etc. It always helps to think of synonyms, as the way one person would describe something is not the same way another would.
Alternative Energy
Environmental Racism
Using the correct words to search will help you find relevant information. Different authors and search tools use different words to describe the same concepts, so it is useful to have a list of similar and related terms in your arsenal when you set out to search for relevant information. The process of creating these alternative terms is called brainstorming terms or concept mapping.

EXAMPLE
Sex Differences AND Communication
If for some reason, you are getting results you do NOT want (say for example you want to find only articles on communication in opposite sex marriages) try a NOT search. Librarians caution that NOT searches often also weed out articles that may have been relevant for you. So only perform such searches if you have LOTS of results (say over ten that are in full text format):
EXAMPLE
Marriage NOT Same Sex
