Princeton University Library consists of many libraries both on and off campus. Environmental materials may be found in many libraries. The primary tool for locating if Princeton owns a particular book or subscribes to a journal is the Main Catalog. Once you locate a particular title, it is important to note the location and the call number. Environmental materials are found in many parts of the classification scheme and under many subject headings.
If Princeton does not own an item, Interlibrary Services can borrow the book or obtain a copy of the article for you. If the item is a book and it is checked out or not owned by Princeton, try Borrow Direct first. It is a very fast way of getting books if owned by Brown, the Center for Research Libraries, Columbia, Cornell, Dartmouth, Harvard, Johns Hopkins, M.I.T., University of Pennsylvania, or Yale. While the Main Catalog will usually tell you if Princeton owns a particular book, Worldcat will show you what other libraries own.
Princeton subscribes to many databases that provide indexing and often the full text of environmental journals. This guide links to various other environmental guides and has resources unique to this guide. It provides an interdisciplinary approach to environmental studies. For a good overview of general sources, see the Environmental Research Guide.
