CLIO is the library catalog for the Columbia Library System (including Barnard Library, but excluding Teachers College and some information from the Law Library). In CLIO you can find books and media materials, search for different kinds of databases, and find articles within those databases as well.
A very large index of books as well as magazines. If the book is out of copyright, or the publisher has given Google permission, you'll be able to see a preview of the book, and in some cases the entire text. If it's in the public domain, you're free to download a PDF copy.
Catalog search tips
If you know exactly what book (journal, video, etc.) you are looking for, you can search by Title, Author, ISBN, etc.
To find items about a specific topic, first try a keyword search in All Fields.
Use "quotation marks" to search for an exact phrase: "economic inequality"
Use * for truncation (to find variant spellings and endings of a word): wom*n will find woman, women, womyn, womxn; activis* will find activism, activist, activists, etc.
For more complex search, use AND and OR:
AND finds records which have all the search terms you entered.
OR finds records which have one of the search terms you entered, as well as records which have more than one of the terms. OR finds MORE.
Use parentheses to group terms: wom*n AND (worker* OR labor*) AND (narratives OR "oral histories")
Subject headings: If you find a book that's relevant, look at its subject headings in CLIO and click through to find more related works.
If a title isn't available via Columbia University Libraries, you may request it via Borrow Direct or Interlibrary Loan (ILL). Try Borrow Direct first for books - the delivery faster and you can check books out for a longer period of time.
