All three libraries in the Union County Library System offer free access to Internet-linked desktop computers. Any adult who wishes to use a public computer must read the library’s computer use policy and sign the computer use agreement. In addition, computer users must present a valid UCLS library card and register at the library’s circulation desk each time to be assigned a machine. The Public Library for Union County also offers a limited number of laptop computers for use inside the library building. Additional registration procedures apply for laptop use. Policies for use of public computers by minor children vary by library.
