BILLINGS, Mont. (AP) — The Billings Library Board has approved a plan requiring parents to give their approval before their children ages 13-17 can access any of the library's unfiltered computers.

City Administrator Tina Volek says only people 18 and older should have access to those computers because the internet has many sites unfit for young viewers.

The current policy is opt-out, requiring parents to write a letter if they don't want their children to have that access.

According to the Billings Gazette ( ), some people are concerned that the filters will block sites that young people need to see, including access to political party information.
