Start with a comprehensive, subject specific library database.
Most of the time you will need to go to a library database to actually obtain the full text of the article anyway -- why not save time and start there?
Also, Google Scholar lacks certain sophisticated searching features you'll find in McQuade library databases. For example in PsycINFO you can limit by population group or in MEDLINE you can limit by age.
Subject and Course LibGuides
McQuade Librarians have created subject and course specific LibGuides or Library Guides to help you get started on your research. Each LibGuide lists how to search for books and articles specifically in the subject covered. For example, if you are searching for articles to support a lab report in your biology class click on the LibGuide for Biology. From the tabs at the top, select the "Articles" tab. You will then see a list of databases with descriptions that will help you search for articles on your topic.
Remember, if you are having problems, librarians are available to help you via phone, text, chat, e-mail, and in the Research Center on the 2nd Floor of McQuade Library.
