    Abstract
    This article desribes the evolvement of computerized information storage and retrieval, from its beginnings in the theoretical works on logic by George Boole in the mid-nineteenth century, to the application of Boole's logic to switching circuits by Claude Shannon in the late 1930s, and the development of coordinate indexing by Mortimer Taube in the late 1940s and early 1950s. Thus, electronic storage and retrieval of information, as we know it today, was the result of two major achievements: the advancement of computer technology initiated to a large extend by the work of Shannon, and the development of coordinate indexing and retrieval by the work of Taube. Both these achievements are based on and are the application of the theoretical works of George Boole
