While not as immediate as articles, books can be incredibly useful to your research, especially for gathering background information. When looking for books, keep in mind that they are written about much broader topics than articles. Even though a book may sound general based on the title, it may have a chapter specifically on your topic.
Use Research@UWW to find books available in Andersen Library and other UW schools. When searching keywords, put the word AND (in all caps) between each word and put quotes around any phrases. For example:
"corporate social responsibility" AND environment
If the book you need is at another UW library, request it for free via UW Request. Click the "Get It" tab, click "UW Request," then sign in with your NetID and password. The request information will be automatically filled out for you; you just need to click "Request." You will be notified via email when the book arrives, usually in 2-5 days, and you can pick it up at the Circulation Desk in Andersen Library.
