OneSearch
OneSearch is a great tool to get a general idea of what is available about a topic and try out some key terms. It searches for everything from books to articles, so you will need to pay attention to resource type when searching. Using Advanced Search, you are able to filter resource type prior to completing a search or you can use the Filter your result side bar on the results page.

If you sign in to your library account using your MyLeo credentials, you can save searches or pin chosen results to your favorites. This will allow you to return to your search were you left off and will keep a record of the terms you used, so you can use them in other databases.
