Let's consider the topic "literature reviews in psychology." How do you obtain information about literature reviews rather than actual literature reviews?
Finding research that is about the subject of writing can be challenging. For example, in the article databases, it is easier to find an article that uses the methodology of a literature review than it is to find an article that discusses how to construct a literature review.
For some of your topics, running searches in the book catalog, the open web, and the article databases will yield a good mix of sources.
