Web Filters

Web filters are software designed to control what content a computer user can access, especially when attempting to view websites on the Web. Though there are a variety of ways to block content on websites, including government sanctioned censoring of materials or websites that can deny access to specific ISP addresses, when used in a library, they are usually in place to prohibit the public from visiting cites that contain material that has been designated as inappropriate.

When it comes to libraries, filters can be seen as both a blessing and curse by some librarians depending on their perspective on the issue. As with technology in general, the convenience that the paradigm offers is not necessarily the reality that is provided. Computer programs that filter materials can be set up to seek out specific words and phrases and prohibit the user from visiting that site. But, as computers are not taught to deal with the intricies of language, a painting like Duchamp’s “A Nude Descending a Staircase, No. 2” might be prohibited viewing due to the word “nude.” I doubt few would describe the image (see below) as even mildly pornographic.


Some libraries have installed filters on computers after the passing of the Children’s Internet Protection Act in 2000. The text of this act can be read here. Other libraries, however, have simply placed appropriate software only on computers that children can access. Still others refuse to use the software altogether, believing that educating children about what is appropriate content to access on public computers along with enforced policies about what can be viewed at the library are as far as the institution should progress in limiting the content that patrons have access to.

Whether the software is described using pejorative labels as “censorware” or more neutral descriptors like “content filtering,” the role of the software is the same. The issue of censorship is an important one to be raised when the software is attached to computers for public use. While few would argue with an individual who wishes to install such software on their home computer to prevent others from viewing such material, the gray middle that separates obscene from artistic is a blurry, seemingly constantly shifting line when it comes to what the public can access.
