There will be times when you need to do a more comprehensive search of the scholarly literature. Here are some tips.
Use Advanced Search
The Advanced Search feature of Library Search can be useful if you need to do a more detailed search as it provides you with additional search boxes and different fields to search by (e.g. Title, abstract etc.)
Searching Google Scholar
If you find one good article in the course of your literature search you can search for papers that cited it. This is a particularly good way of finding key articles on your topic if you are struggling to find relevant papers.
Key in the article in library search and select Google Scholar. Look for the link Cited by and view the papers that have cited your paper.
