When searching, you will often end up with results that do not help answer your research question or provide evidence.
Instead of reading articles or book chapters that will not be useful for your assignment, look for clues in the citation and abstract.
The citation contains useful information such as the article title, journal title (or book title), publication date, and subjects, which provide valuable clues about whether or not this is a good match for your research.
In many databases and the library catalog, you can click on the title of the article or book to read the abstract or a short summary. This abstract will give you a clear idea of whether or not the article or book is relevant.
