This is the second of two articles describing the development, testing, and evaluation of the Individualized Instruction for Data Access System (IIDA). The system was tested in an industrial setting and it was demonstrated that (1) end users of scientific and technical literature could learn to do their own bibliographic searches through computer‐assisted instruction as well as they learned through a comparable period of conventional instruction, and (2) end users were as satisfied with the results of their own searchings as with the result of searches performed for them, for the types of searches tested.
