A method and a system for locating and accessing information on a continuous image presentation medium, such as information from a video medium, e.g. a video tape or disk. The system and method use an index which contains topics of interest on the medium and a code of indicia, such as a time elapse code identifying a portion of the video tape or disk in which desired information may be obtained. Corresponding time elapse codes are visually presented on the video images. Thus, the user will locate the time code from the index representing the time elapse period from the beginning of the tape or disk and move the tape until the time code is identified visually on the visual presentation from the tape or disk. In a preferred embodiment, the video or other visual presentation is used with printed material. The printed material may adopt the form of a multi-page document, such as a manual, and the manual may be provided with an index for identifying pages from which selected information may be obtained. In addition, the manual or the index, or both, may also contain indicia, such as time codes, identifying certain portions of the video tape in which corresponding information may be located.
