This special section contributes to an inclusive cognitive model of information problem solving (IPS) activity, touches briefly IPS learning, and brings to the notice methodological pitfalls related to uncovering IPS processes. Instead of focusing on the IPS process as a whole, the contributing articles turn their attention to what is regarded the heart of IPS, namely the evaluation of information. In this commentary we reflect on theoretical, methodological, and instructional design issues. Results are commented upon and future research is addressed. A vignette is presented to illustrate the aforementioned issues. (Contains 1 table and 1 figure.)
