Rapid City Public Library card holders will no longer be able to access just anything on the computers.
After a report to library staff and alderman Chad Lewis about an individual watching pornography on a computer, the library board of directors took action.
Now, every computer is equipped with a filter, not just the PC's in the children's section.
At Rapid City's Legal and Finance committee meeting Wednesday, alderman Chad Lewis said his concern was for the safety of the children at the library.
"I have no desire to tell people how to live their lives, I just care about kids; pure and simple," Lewis said.
While the board's action is a relief for some, others say it infringes on their rights.
"I think we should be able to use it for whatever we want too. We do sign an agreement when we use that we won't use it for anything fraudulent or in bad taste," said Ken Davidson.
Library officials say adults can ask to have the filters removed for specific searches that may be blocked as a result of the filter.
In a post on the library's website, Director Greta Chapman said: "In the last two years 907,655 people used the Rapid City Public Libraries, logging 256,050 hours on public Internet computers. During that same time period, there have been 38 incidents of individuals viewing inappropriate websites that have been addressed by staff and resulted in loss of library services.
In 90 days, the library staff will do a review to see if the filters are working.
