Reference Sources are an excellent place to start seeking information!
Academic libraries buy or subscribe to a LOT of reference resources. They are a reputable starting point to launch questions that narrow your focus.
Annual Reviews has provided researchers with a definitive academic resource in 44 scientific disciplines, including psychology, clinical psychology, public health, sociology, etc. since 1932.
They synthesize the vast amount of primary research literature and identify the principal contributions in included fields. Editorial committees comprised of the most distinguished scholars in the discipline select all topics for review, and the articles are written by authors who are recognized experts in the field.
The summaries include keywords, an abstract, an introduction to the topic addressed, and include extensive lists of cited literature.
Here is a tutorial that covers website features, and how to navigate, access, and search effectively across Annual Reviews content.
These are examples of the type of reference materials available in print--they are located in either the reference collection (on 1st floor) or in the stacks (1st floor).
Find them by limiting the online catalog to the location "Reference Collection" and typing in appropriate keywords.
