Our Interlibrary Loan system via the Kansas Library Catalog enables you to access some 4,000,000 books, tapes, compact discs and videos in over 300 Kansas libraries. Library staff will contact you when your request arrives at the library or if there are any problems. Each patron is allowed up to three requests (including ILL titles already checked out) on the system at any time. You may place ILL requests either at the Derby Public Library or online from your home or office by using the form below.  “Reproduction of works protected by copyright may be an infringement of the copyright law (Title 17, U.S. Code).”
