ABSTRACT:
A binder, particularly for use with paper-back books, video cassettes and other parallelepipedal objects, has a front wall and two spaced rearward side walls which, when unconstrained, are convergent but capable of being sprung further apart, each side wall having externally a recess bounded by a shoulder, the respective shoulders of the two side walls facing in opposite directions such that when a plurality of the binders are placed side by side in a row the shoulder of one such binder can abut against the shoulder of the next such binder to locate the binders in alignment.
