The challenge for research in Environmental Studies is that there is no single database that effectively covers the literature for all potential topics in Environmental Studies in sufficient depth. Use several databases to discover resources that relate to your topic.
Many of the databases listed on these pages cover a variety of publication types: books, journal articles, news & magazine articles, government reports & documents (international, federal, state), and unpublished research reports.
The items with a star 
in each section are the best databases to search.
