Research is a process and although it seems to have a starting point and an end point with several discrete steps in between, the process is more like a map that asks you to retrace your steps now and then in order to reach your goal.

Depending on where you are in the process, you can find strategies and resources to help you along every step of the way:

Develop a Research Plan
understand your assignment; know where to go with questions; select your research topic

Do Background Research
use reference sources; develop and refine your topic; identify a research question

Create a Search Strategy 
identify key terms and phrases; map concepts; understand search options and sources

Find Sources
use library resources to find books, articles, and more; use Google and Google Scholar

Evaluate Sources
understand evaluation criteria;

Put it Together
write with sources; create a bibliography
