When you have a research project, you need to set up a system for keeping track of the sources you find and other information you collect during your research.

There are several citation management tools available:
Note: Many library databases also allow you to gather sources in a folder that is accessible while searching in that database. EBSCO and Proquest databases, for example, have this function. However, keep in mind that you will probably still need a way to organize your sources when no longer accessing the given database.
