What about folded Essential Geography maps ?
When not left flat, my maps fold like accordions - the easiest style for human beings to refold. The folded "Essential Geography of the USA" map features an atlas fold that allows you to read across the country as if you were turning the pages of a book.
Also, the special high-strength paper on which I print my folded maps allows you to reconfigure the folds to suit yourself. Folded maps don't take up much space. Plus, there is a certain aesthetic to a map that lets you isolate your geographic focus by letting you fold the map sheet down to just your region of immediate concern.
