Google Books can be a good source for electronic versions of books.
Use the Libraries' ADVANCED SEARCH to find book on your topic in the WMU collection. Click on the Books and Media tab.
If you already know the title or author, use the pull-down arrow to select Title or Author.
When looking for books by topic, enter you keyword(s) into the search boxes.
SEARCH TIP: If you are using a phrase in your search, be sure to put it into quotation marks, e.g. "income inequality"
SEARCH TIP: Use an asterisk * to pick up variant endings of a word, e.g. financ* with retrieve finance, finances, financial, financing, etc.
