Google Scholar should not be your first resort, however, you can find useful articles using it as a tool. First you will need to ensure that Google Scholar is communicating with the UofT catalogue, otherwise it will likely ask you to pay for articles. Here is how you adjust the settings:
1. Go to google scholar.
2. Select settings in the upper right hand corner.
On the Library Links page, enter "university of toronto" in the search box. Check all relevant check boxes and click on save. You are now ready to search.
