For interdisciplinary work in the areas of health, environment, climate, and policy, your best bet is
OneSearch - just use the box on the library home page.
It searches a whole range of databases the library subscribes to and then you can easily link to peer-reviewed articles and books we have online.
Other good databases include:
Scopus is the largest abstract and citation database of peer-reviewed literature: scientific journals, books and conference proceedings.
To click through to the database, click on the San Diego State University, San Diego option.
If you aren't finding information on your topic, going to more specific subject guides might help.
