In the field of library science wherein literary, artistic and shelved collections of various materials are descriptively classified by rows of catalog cards maintained upright in open top, pullout drawers, a rigid, inexpensive, light weight, V-shaped, suspendible separator, provided with an upwardly open, finger-clearing mouth, has a handle integral with its rectangular, transparent, rearmost leg for ease of insertion in a chosen drawer between a pair of pre-selected cards, operating to maintain the two cards tilted in opposite directions such that the card engaged by the transparent leg therebehind is conveniently held at a proper, rearwardly tilted angle for full, unobstructed viewing through the transparent leg of the call number and other data on the front face of the rearwardly tilted card, thereby freeing the hands of the user for rapid, accurate copying of all or portions of such data as may be desired without risk of losing his place. A central notch across the apex or bight of the separator clears the card-retaining rod of the drawer such that the transversely arcuate bight of the inserted separator rests on the bottom of the drawer.
