Dynamic text is an information retrieval system that redisplays text fragments so that they always appear to be in a linear sequence, even though the user is following links. We compared information retrieval tasks using dynamic text and paper text. Dynamic text was better than paper text when answering difficult questions. We also found practice effects in the use of dynamic text. A personality measure, locus of control, was part of the study. Internal locus of control users were faster than external locus of control users.
