The tools below will allow you to search for book information, and in some cases obtain free online books.
NOTE: Couresy Card Holders, Alumni, and Emertus professors have access to the paper book collection through our online catalog. For additional information see the "Loan Periods, Renewal Limits and Fines" section of our Policies page.
One excellent resource for searching the full text of millions of books is Hathi Trust Digital Library or http://books.google.com/, which provide access to the fulltext of materials now available as public domain materials (published prior to 1923). In addition, if the publisher has given permission to Google, other books are available for preview or full-text access. For newer materials you can see snippets online, but you must obtain the complete books through your local public library.
Another excellent resource for searching into new books is Title Preview by ebrary. This tool will allow you to discover information about books of interest. An account is required for fulltext access, so you will need to go through your local library to obtain access to either a paper copy or a subscribed online copy.
One additional free search tool to consider is Summon (from Princeton). You will see information within books and other materials...but you will not have links to the full text materials.
