    Abstract
    Vannevar Bush's famous article, 'As we may think' (Atlantic monthly 176(1945) S.101-108) described an imaginary information retrieval machine, the Memex. The Memex is usually viewed, unhistorically, in relation to subsequent developments using digital computers. This study reconstructs the little-known background of information retrieval in and before 1939 when 'As we may think' was originally written. The Memex was based on Bush's work during 1938-40 in developing an improved photoelectric microfilm selector, an electronic retrieval technology pioneered by Emanuel Goldberg of Zeiss, Ikon Dresden, in the 1920s. Visionary statements by Paul Otlet (1934) and Walter Schürmeyer (1935) and the development of electronic document retrieval technology before Bush are examined

    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
