A scoring procedure for Guttman scaling is presented & associated IBM sorting operations described. The procedure assigns a unique score to each unique response pattern &, unlike Ford's earlier technique (Pub. Opin. Quart., 1950, 14, 3, Fall, 299-304), can be used for scales composed of more than 6 items. The procedure requires that items be in the form of dichotomies. The key to the procedure is to group items into sets of 2's &/or 3's & assign numbers to the few possible permutations & combinations of responses to 2 or 3 dichotomous items, data needed to describe a scale are reduced by from 50-67%. Consequently, time required for scaling, particularly IBM punching & sorting, is substantially reduced. W. Delany.

When difficulties were encountered in programming the Farr-Jenkins-Paterson revision of the Flesch formula for the UNIVAC 1105 computer, the authors derived a new formula better adjusted to machine capabilities. They found it works twice as fast.

Using a sample of 90 dailies with reference to 23 presidential campaign events, two University of North Carolina journalism professors report on the completeness of coverage of events and the amount of coverage made available to the average reader—a figure ranging between 41% and 60%.

Analyzing data gathered in studies of three different "news breaks," the authors describe apparent regularities in the diffusion process and note differences in the functions of the newspaper and broadcast media. Other findings suggest that person-to-person "relay" may be of limited importance.
