When you use the Cornell University Library homepage to search for "Articles and Full Text", what you are really doing is searching Summon, (If you have more-specialized searching to do, you can also go into individual databases for your searches).
Summon (Articles & Full Text) searches articles, ebooks, audio files, and video files. It does not search the library catalog (print books and other physical items). The diagram at left shows what Summon does and does not cover.
Use the Library Catalog for print books (although it also includes all of our e-books).
