This is an old article, but some good brain food for those information architects out there. A good primer on some different ways people try to find content.
In my work on intranets and complex websites, I noticed a range of situations where people didn’t necessarily know what they needed to know. Additionally, when I opened my browser history to look for examples from recently-visited sites, I noticed that the majority of my own time was spent trying to find things that I had already discovered. These two modes didn’t fit into the concepts of known-item and exploratory information seeking. I call these “don’t know what you need to know” and re-finding.
I spent a while letting this rattle around my head, talking with IAs and designers, and realized that most only thought in terms of known-item searching. When discussing the other types of tasks, they’d ask with a horrified look, “So how do you design for that?”
