Here's a press release from our local library system:
Library customers are advised that there will be no computers or WiFi service available at any Pima County Public Library branch locations on Sunday, July 17, because of county-wide maintenance work.
Library officials are aware that many customers rely on public-use computers, and so wanted to help those customers avoid unnecessary trips to their library on Sunday. While the libraries will be open for other services such as book checkouts and returns, the library staff also will be without computers.
Computers and WiFi will be restored by the start of business Monday.
