Interlibrary Loan Request

Would you like to borrow an item that the Mercer County Library System (MCLS) does not have in the catalog? Complete and submit the online Interlibrary Loan (ILL) Request Form below to ILL request an item be loaned to you from another library outside of the MCLS. The ILL Department will reach out to you if they encounter any issues in fulfilling your ILL request. This service is often useful for temporarily obtaining specialized, expensive or older items.

For more information, please review the full ILL Policy.
