ABSTRACT:
A platform assembly is provided with a raised edge at the bottom against which a bottom edge of the open book rests. A securing device is provided with a bar with a hook at each end of the bar, first and second prongs extending downwardly from the lower side of the bar, first and second shafts mounted to the front side of the bar, and first and second restraining wheels secured to a corresponding one of the shafts by opposing springs mounted to each of the shafts. The securing device is installed on the platform by sliding the hooks over the upper side edges of the platform. The prongs of the securing device are positioned over inner sides of the front and back covers of an open book to secure the book to the platform assembly. The open book is positioned such that rounded tabs of the platform assembly and the restraining wheels of the securing device maintain the pages of the book in an open orientation. A selected page of the open book is turned by applying manual pressure with one or more fingers in a direction of the turn such that the selected page slides free from a first restraining wheel and a first rounded tab. The selected page is then positioned behind the second restraining wheel and the second rounded tab.
