Where to start will depend on the research you are doing and the type of information you need to find.
A great place to begin is to check out CREDO topic pages for your subject. These pages are tied to not only Credo Reference, but also our catalog, numerous databases and ebrary.
Once you know your topic, when choosing keywords it's always a good idea to start broad and pare down. An excellent strategy for this is to take the exact words and/or Psychologist directly out of the table of contents. As an example, try copying and pasting these keyword/keyword combinations into the above box.
Can you think of more? If you have found keywords that have worked please add them to the comments section below!
TIP: once you have your results, sometimes it is helpful to use the filters on the left, such as date range, availability or resource type.
