Interlibrary Loan (ILL)

Interlibrary Loan (ILL) is a free service through which you request materials not owned by libraries in Washington County, but may be borrowed from other libraries.

How to submit an interlibrary loan borrowing request:

Things to know:

  • Please allow a few weeks for processing and mailing.  You will be notified when your item is available for check out.
  • Limit of five active requests per person. Items currently checked out to you do not count toward the limit of five.
  • Loan periods for materials will vary.
  • Console video games (Wii, PlayStation, Xbox, etc.), e-books, and e-audiobooks are not available through interlibrary loan.
  • Requests for materials published in the current calendar year should be submitted as purchase suggestions to your local library.
  • Return Interlibrary Loan materials to the same library from which you checked them out, because they are carefully tracked by library staff.
