Support for a book or an electronic tablet

A support for a book, comprising:

• a rectangular back panel, a top panel connected by a first top hinge to an upper edge of the back panel, the top panel being formed of a first top panel section connected by the first top hinge to the back panel and a second top panel section connected to an upper edge of the first panel section by a second top hinge that extends parallel to the first top hinge, and at least one side panel each connected to a side edge of the back panel by a corresponding side hinge that extends transversely to the first top hinge, such that the support is configured to transition between a compact configuration for storage, a lectern configuration, and a bookrest configuration, wherein in the compact configuration, each of the panels lies in a plane parallel to each of the other panels so as to minimize the longitudinal and lateral space occupied by the support, wherein in the lectern configuration, when the support is placed on a tabletop, the back panel and each of the at least one side panel are disposed in upright planes, relative to the tabletop, that are inclined to one another and the top panel is disposed in a plane parallel to the tabletop, so that both sections of the top panel rest on an upper edge of each of the at least one side panel, wherein in the bookrest configuration, when the support is placed on a tabletop, the back panel is disposed in a plane parallel to that of the tabletop and the sections of the top panel are hinged relative to one another and relative to the back panel, to permit the second panel section to serve as a support surface for supporting a book in a plane inclined to the plane of the tabletop, when a free edge of the top panel rests on the back panel or a side panel.
