| Abstract: | The present author notes that G. J. Hornik describes, in the May issue of the American Psychologist (1963, 18, 260-261), a variation on the method of retrieval of references using 10- column cards, which was described in an article by the author in March 1962. Instead of stamping the index number of the reference on the Uniterm cards as the present author does, Hornik prefers to use punched cards with holes located in predetermined positions according to the reference number. The author discusses the problems seen with using Hornik's method. (PsycINFO Database Record (c) 2010 APA, all rights reserved) |
