    Abstract
    This experiment explores the effectiveness of retrieving the listing of a known-item book from the 3.6 million entry onine catalog at the library of the University of Michigan using various combinations of author's name plus first and last title words. The principal finding was that 98.9% of the time a 1 to 20 line miniature catalog (minicat) was displayed that contained either the entry sought or a not-in-database (NID) reply when the search comprised all three words.

    Abstract
    Authority control is discussed from two viewpoints: The need for bibliographic records relating to a name to be brought together under one form of the name; and the need for cross references to direct a user to a heading from variant forms of the name. Data from two research projects that support the need for choosing one form of name are summarized. The author's study of user requests that resulted in no "hits" in an online catalog is described. Data are given to show that for only 6.4% of these requests would our current methods of cross referencing in authority records have been helpful, and that two system programs would have given much greater assistance.
