ABSTRACT:
A bookshelf has a guideway formed longitudinally therein. A channel structure is attached to the shelf within the guideway and includes at least one row of spaced, open-ended apertures. A base is connected to a planar book support member and has a movable lock bar extending therethrough. A cross bar is attached to a second end of the lock bar and is urged by a biasing spring engaging the second end of the lock bar to a first position in which the cross bar is securely engaged in one of the apertures in the channel structure to lock the base and the attached book support member in a selected position along the length of the shelf. One and preferably two identically constructed bases and attached book support members, each having a lock bar mounted in each base, are adjustably and lockingly positioned on the shelf.
