Apparatus providing indexing of transcribed information recorded on a recording medium. Information denoting end of dictated message, special instructions of the dictator, or other details, is recorded directly on the recording medium rather than being marked on a separate index member by the dictator. An index member not requiring predetermined beginning and end indications is traversed by transcription apparatus concurrently with a traverse of the tape or other recording medium, and a visual indication is applied to the index member corresponding to each element of information previously recorded by the dictator. When this preparation of the index member by the transcriber has been completed, a reference mark is positioned adjacent the index member mark which indicates the beginning of dictation to be transcribed; the index member then moves relative to the indicating mark as transcription progresses to indicate the transcription relative to the previously-prepared index member.
