To find books at the University of Illinois, begin with the library catalog. Most patent resources are listed under the subject heading "patent."
Still no luck? You can use Interlibrary Loan to request books and articles. This requires a valid NetID.
Want the latest titles? See the "New Books at ACES Library" on the Funk ACES Library Resources tab.
And, of course, ask a librarian if you want to find more!
