The search box on the library homepage searches all library systems--the catalogs, articles, and library websites.
The library catalog contains all of the holdings of all Cornell University libraries including records for books, ebooks, DVD's/videos, sound recordings, magazines/newspapers/journals, online journals/newspapers, computer files, government documents, manuscripts and archives, maps, musical scores, and more. Everything but articles!
From the list of results, you can "Limit your search" by format, language, year, and more.
"Looking for More?" From the list of results, select "Request from libraries worldwide" (Worldcat Local).
The advanced search allows for more precision, offering multiple search boxes and search options. The drop down menus with each search box allow you to specify whether you want to search "all" terms, "any" term, "begins with," or terms as phrases. The next drop-down menu allows you to specify where to search for the terms -- in the Author, Title, Keyword, Subject, etc.
