Make sure the secondary sources you consult are as up to date as you can find. Both the background information and the citation finding benefits are diluted if you look at sources that are out of date.
If searching for secondary sources online:
Use the Locate (Westlaw) and Focus (Lexis) functions to help you browse the materials.
Avoid printing out lengthy documents that may prove to be marginally relevant.
Try natural language searching if you are not familiar with the jargon.
Use appropriate date and title field restrictions to cut down on the volume of search results.
Remember that lengthy secondary sources may be easier to browse in print format.
Don't spend too much time on a particular source if you are not finding helpful materials.
Remember that secondary sources are essentially used to speed up the process of locating, and enhancing the understanding of, the primary source materials which are the objective of your research effort.
