Start with CLIO to find books and journals in Columbia University library collections. (Use the Pegasus catalog to find books and journals in the Law Library collection and Educat for resources in the Teachers College Library.)
Then try WorldCat, the largest online catalog in the world, with over 100 million book and journal records.
To find dissertations, start with Proquest Digital Dissertations. Also check Dissertations & theses. UK & Ireland and DART, Europe's E-theses portal.
For print periodicals and microforms, see the Periodicals and Microforms Reading Room, (Butler 401).
Other essential resources include:

- Borrow Direct
Borrow Direct enables Columbia University students, faculty, and staff with library borrowing privileges and active e-mail accounts to request material from Brown University, Cornell University, Dartmouth College, Harvard University, Johns Hopkins University, MIT, the University of Pennsylvania, Princeton University, and Yale University.
