General borrowing privileges have remained consistent throughout the decades: http://www.library.illinois.edu/borrowing/ and http://www.library.illinois.edu/ugl/about/circulation/
However, certain materials offered at the Undergraduate Library are restricted to those with UIUC identification (iCards), such as the loanable technology, reserves, and eaudio collection. Additionally, the media (including dvds, video and tabletop board games) have some restriction for community users.
