A large rectangular map, or chart, that is reduced to small and uniformly-sized display areas, in a top half section and bottom half section, having leaves in each section for easy directional leafing (right to left, left to right, up tab, down tab) to all selected display areas. There is no folding or unfolding. This leafing format is made possible by simply making three folds horizontally (inward, outward, inward), cutting a slit along the horizontal centerline between the right and left edge panels, fanfolding lengthwise into an odd number of vertical creases that form a vertical strip of the eight right edge panels, making a single horizontal fold of this strip into a tab, and abutting the four corner panels to create the base map paging format of four panel display pages. A foldable cover is required to anchor the format for permanency, stability, and storage. The size of the display pages and the folded cover can be controlled by the number of vertical folds lengthwise; more odd number of folds produce a smaller map; less folds a larger map. Current maps are generally machine folded for storage; fanfolded lengthwise and two-folded vertically. They require unfolding and refolding. Many have covers only for presentability. This invention contains convenient features for use in small areas as: no unfolding and refolding, ease in opening for use, ease in closing for storage, ease in paging to all map areas, and mobility for changing viewing angles.

[ I claim:] [1.] A map or chart with an upper edge, lower edge, left edge, right edge, a front surface display area of four panels of contiguous topographical or diagrammatic features, multiple leaves rooted between the vertical edge panels for accessing all other display locations, a cover to make permanent and stabile the leafing format and for folding for storage, said map comprising:A. three horizontal evenly spaced folds that form four panels, the first from the top an inward fold, the second an outward fold at the centerline, and the third an inward fold, and an odd-number of vertical folds of three or more, alternately folded inwardly and outwardly to form double leaves between the single-leafed left and right edge panels, the resultant folds causing an even number of multiple panels, andB. a slit along the horizontal centerline's outer fold line between the inner edges of the left and right edge panels which slit enables the map to be divided into a top and bottom section with leaves that can turn independently of each other, andC. from the map's unfolded open position, fanfolded the vertical outer folds into leaves, overlayed them onto the left edge panels with the right edge panels remaining open, abutted the left and right edge panels, resulting in a two-panel wide strip of the right side panels, andD. an outward final fold at the horizontal centerline fold to form a horizontal leaf, to adjoin the inner edges of the four corner panels, to overlay the leaf upon the bottom panels, to position all leaves between the side panels along the vertical centerline, resulting in the base configuration for the map paging format and a display page of the top section's right-most four panels.
