ABSTRACT:
A book rack of selective capacity includes end members and a base extending longitudinally between the end members, the base having an undulate configuration including undular support members and an undular basal member, the undulations being in a flexible conformable material such that the length of the base may be expanded and contracted selectively into conformance with a particular longitudinal length by bending of the undulations, thereby providing a longitudinal spacing between the end members corresponding to the desired capacity of the book rack.
