Abstract

A book support of the type used to support books of an old or delicate construction allows the books to be opened and held steadily. The support (10) comprises an upright platform (11) which is rotatable about an axis (A) and a horizontal platform (12) which is suspended below the plane (A-C) in which the axis (A) lies. Horizontal platform (12) is rotatably suspended at the end nearest the axis (A) and at the end furthest from the axis (A). Thus, horizontal platform (12) can be moved upwards and away from vertical platform (11) as the pages of a book are turned from lying against horizontal platform (11) to lying against vertical platform (12).
