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.

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.

Use WorldCat to search the holdings of libraries around the world, and find items to request.
