What do we really know about information architecture? Do we know what works? Can we defend our designs? Are we improving? In preparing for my upcoming seminars, I revisited the role of research in the design process, and surveyed the literature most relevant to the practice of information architecture.
It was hard work. When it comes to information architecture research, the knowledge environment is highly fragmented. But I was able to extract a few gems and gain some new insights.So, for all those information architects who didn’t spend their summer in a research library, here’s a brief summary.
Research in Context
Before we dig into the research itself, it’s worth considering the myriad inputs that shape design. They include:
- Goals and Scope. The stated project goals and scope which may be conveyed in an RFP or as functional specifications.
- Constraints. The budget, schedule, project team, and technology infrastructure.
- Discovery. Project-specific research to learn about your unique blend of users, content, and context.
- Competitive Analysis. Reviewing what everyone else is doing and borrowing from the best.
- Expertise and Experience. What you already know, including explicit and tacit knowledge.
- Guidelines. Published heuristics and guidelines derived from research and/or practice.
- Published Research. Results of academic or corporate research in human-computer interaction, library and information science, cognitive psychology, etc.
- Usability Testing. Iterative project-specific testing of prior designs and new prototypes.
The information architect must somehow process each of these inputs and reconcile the differences. That’s the hard part.
What happens when one input contradicts another? Do we trust a guru’s guidelines, a researcher’s results, or our own gut instinct? How do we evaluate benefit to the user against cost of development?
Any literature review should be mindful of the critical role of judgment in determining which research applies in which context.
So, caveats aside, here’s a radically incomplete and idiosyncratic list of freely accessible research papers worth review before you plunge into your next information architecture project.

What I’ve Missed
I’m sure that I’ve committed many egregious sins of omission, so please share your favorite research articles and sources.
After all, we know from the research that collaborative information retrieval is a pretty good strategy. Let’s share what we find, so we can focus on the hard part of figuring out how to integrate what we learn from research into the practice of information architecture.
