- 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

- Abstract
- This experiment searches an online library catalog employing author surnames, plus title words of books in citations of 8 scholarly works whose authors selected the title words used as being recallable. Searches comprising surname together with two recallable title words, or one if only one was available, yielded a single-screen miniature catalog (minicat) 99.0% of the time
