IL2009: Trying Not to Filter: Internet Filtering Technologies Update

Tuesday morning I headed to a presentation in the Internet @ Schools West track given by Sarah Houghton-Jan on Internet filtering.

Some of the key points from this session:

  • Filters do not work because the current definition of obscenity does not work on the Internet.
  • Accuracy of filters is still an issue–in both directions–filters both over block some good material and under block objectionable material.
  • Sarah spent months testing filters and found that among the four she tested, the accuracy for filtering text-based Web pages was 81%, accuracy for image searches 44%, and accuracy for e-mail attachments 25%.
  • 81% was the best rating out of all the filters tested for any category.
  • When patrons hit a blocked site they will most likely be too embarrassed to ask for legitimate sites to be unblocked.
  • Examples of legitimate sites that were blocked: WebMD, wikipedia entry about Hustler, WWII history site, National Geographic site about beavers.
  • It’s not only commercial Web sites that were blocked. The library’s own online resources were blocked.
  • It’s also easy to get around filters with portal sites or sites that allow you to click through via a thumbnail image. Adult images on Web pages that did not have sexual text were not blocked. Sites that contained misspelled words such as pron or pr0n instead of porn were not blocked.
  • Sarah cited other studies conducted between 2001-2008 showed about the same ratings as SJPL.
  • In sum, “All filters block a wide range of constitutionally protected content in attempt to block other content.”
  • Filters falsely block many valuable web pages and other online resources such as war, genocide, safe sex, public health.
  • If you have filters in place advise your customers what their experience is going to be like and that good sites WILL BE BLOCKED.
  • Do not send the message to parents and patrons that filters will protect children.
  • To combat filters: use stats from other studies, do good research, collect anecdotal stories.
  • Final result for SJPL: Filtering was not put in place. Now there is a resolution to NEVER filter so it can’t come up again.
  • Price makes a difference. The more you pay the more flexible the filter is. You really get what you pay for.
  • “ERATE isn’t worth it” for filtering according to Houghton-Jan. Have to figure in other costs…staff time for research, install, maintenance.

One of the key take aways from this session is that if you are living with filters in your library, education for the community is key. If you want to fight filters take a look at the work already done by San Jose Public Library.

Bill to Ban Facebook in Libraries

When I was about 8-years-old I was walking home from my bus stop after school and a car stopped beside me. A man opened the door and offered me candy. In my mind I knew better, but like a typical kid I wanted the candy and walked towards the car. As I approached the car the door opened, and the man reached his hand out to grab me.

Does this sound like an urban legend?

It might, but it did actually happen to me. Luckily my parents had taught me stranger-danger. That and I was also a pretty tough kid. I slammed the car door (I think I may have crushed his hand), and ran home. If things had gone differently I may not be here tonight typing this post. I get chills thinking about it–especially now that I am a mom.

I am living proof that stranger-danger is real, but you don’t need me to tell you that. The news inundates us with stories of stranger-danger even though statistics tell us that most offenses to children are committed by someone who is not a stranger but is in fact someone close to the child.

What I am really here to say is that it’s important to educate children so that they can make smart decisions in any circumstance.

From USA Today:

Congress is considering a bill that would bar children who use computers in public libraries from accessing Facebook and other social networking websites without parental permission.

This has to be one of the most ridiculous things I’ve heard recently.

First, how will we define “other social networking websites” when pretty much every site is becoming a social networking site? Has anyone in Congress heard of Web 2.0?

Second, how does this teach children to think for themselves and make smart choices? We cannot block every site where a predator could be lurking just as we cannot place children in a bubble when we send them out the door to school every day.

As librarians and library staff we have to advocate for educating our public officials, the media, parents, and children about the real dangers of the Internet – ignorance.

If you haven’t yet take a look at the ALA Libraries & the Internet Toolkit. Most of the content is dated 2003, but it is still relevant.
