    Abstract
    This article reports the findings of an experiment using a simulated title pages, author surnames, and title words, one-third of which were selected by each of the 3 authors, to determine the frequency of one-screen displays when used to search for known items in an implied Boolean retrieval system. Searches comprising surname plus one significant title word produced one-screen displays 78% of time; surname plus 2 words 97% of the time; and surname plus 3 words 98,5%. Three quarters of the significant words were nouns
