The San Diego County Board of Supervisors voted Tuesday to prevent minors from checking out R-rated movies at county libraries.
"I think a lot of parents, from the phone calls we got, didn't realize that by signing their kids up for library cards they were allowing them to check out videos and DVDs containing violence, sexual content and adult-themed material,'' Supervisor Bill Horn said.
At theaters, an R rating means anyone 17 or younger must be accompanied by a parent or an adult guardian.
The new county policy changes video check-out procedures, forms and software to provide an option for parents to restrict their children's access to R-rated movies, according to Horn's office.
The change will result in a one-time cost of about $5,800 for recataloguing R-rated materials and changing forms.
