When you first start learning about a new topic it can be helpful to do some background reading to find reference material or encyclopedia articles that will cover a topic more broadly to give an overview or introduction. For Philosophy, the following databases are good places to start looking:
In the Gale and Oxford databases, start searching for background reading by typing a philosopher's name or a philosophical idea into the search bar.
In LION to search for background reading, type your keyword into the search bar and select "Reference Works" under "Content Type" before clicking Search.
You can also filter your results in LION to be reference only by selecting "Reference Works" in the left column of the search results page.
