Abstract : The logic of a multi-level file structure as a frame of reference for measuring user interest was tested in an exercise using 39 subject specialists to evaluate a random sample of 444 documents drawn from a population of approximately 50,000 documents. The measure (accessibility scale) proved to have low reliability (.44) but yielded multiple correlations as high as .75 with a cross validity of .68 with sets of 5 to 7 independent variables in the regression equations.
