1. In a data processing and display system, a computer executable process for simultaneous visual depiction of plural text hierarchies of a visually displayable machine readable text, including provisions for a visual cue as to a location of a user select text within the simultaneous visual depiction of plural text hierarchies, the process comprising the steps of: a. extracting a text hierarchy for a reader select text of a machine read text accessible by at least the data processing portion of the data processing and display system, elements of said text hierarchy selected from the group consisting of, in descending rank order, volumes, sections, subsections, chapters, pages, paragraphs, and sentences; b. formatting for display and displaying upon a display of the data processing and display system, units of a select element of elements of said text hierarchy as horizontally tiled plane sets, and units of an immediately subordinate rank order element of elements of said text hierarchy as vertically tiled plane sets; and, c. selecting a portion of text of the machine read text present in said select unit of a select element of elements of said text hierarchy such that when said selected portion of text is present in a hierarchy represented by a horizontally tiled plane, units of said select element of elements of said text hierarchy move apart substantially vertically, and such that when said selected portion of text is present in a hierarchy represented by a vertically tiled plane, units of said select element of elements of said text hierarchy move apart substantially horizontally, said selected unit of said select element of elements of said text hierarchy being further away from at least one other adjacent unit after said movement.
