Bhavnani, Suresh K.; Bates, Marcia J.
Proceedings of the ASIST Annual Meeting, v39 p204-13 2002

Pinpoints strategies that are known by expert searchers; why such knowledge is difficult for novices; and how the analysis provides testable predictions of behavior based on the acquisition of different types of knowledge.
