The association does not endorse the use of filtering software in public libraries , because it is known to block legal material that library users may find useful for their jobs, studies, health and other needs. The software also does not fully protect children. The association strongly encourages local libraries to adopt policies and practices that govern Internet use in the same way they adopt other policies to ensure a positive library experience. The association also takes an active role in educating the public about how to use the Internet and encourages local libraries to play a leadership role in their communities. Almost all libraries offering Internet service have such policies and programs.
Libraries report few complaints about Internet content from their users.
The library now has a policy that permits adults to choose computers with or without Internet filters. A second suit filed by the mother was also dismissed. Some filters can be set to reject the message or to forward it to a system administrator for review if a listed word is detected. Sometimes a message may be sent informing the sender that the message has been blocked. Filters that block according to the originating site are most commonly used to restrict Web access.
