The archives have their own database and the holdings cannot be searched through the library catalog. Archon is available at http://archives.library.illinois.edu/archon. The archives database, Archon, is structured quite differently from the library database. Instead of the call number, you will need to record the record series number, like a call number you will need it when requesting any file from the archives. See "Searching Archon" below for more general information on searching and see "How do I read an Archon record" for detail.
