Abstract

In information retrieval system includes a help feature, wherein a help key on a terminal can be actuated and a host computer responds by determining the identity of a page of basic information being transmitted at the time the help key is operated, determining the location of a page of subsidiary information associated with the currently transmitted page of basic information, and transmitting that associated page of subsidiary information to the terminal for display thereby. A system guide aspect enables the system to provide guide information adapted to assist in the use of other data subgroups. A bookmark facility involves the use of a mark request key on the terminal and a mark record device operable in response to the actuation of the mark request key to create a record of the storage location of the one of the pages being transmitted to the terminal for display thereby at the time of such actuation. A search request key on the terminal enable transmission of a search request to the host computer.
