Information storage device and method

An evaluation method, comprising:

• providing a card-like body having a front panel, a rear panel, and means defining a space between said panels and a plurality of parallel slideways in said space, each slideway having an end opening at an edge of the body;
• providing a plurality of like slide members, and positioning one in each slideway, with each slide member having an end portion projecting outwardly of the edge of the body and from the end of the slideway, to serve as a pull tab;
• providing a strip of like indicia on each slide member and a corresponding strip in indicia inside of the body adjacent the slideway;
• providing indicator means on the slide member and positioning such indicator means and the two strips of indicia such that when a given slide member is moved to expose a particular element of indicia immediately outwardly of the body, adjacent the entrance to the slideway, said indicator is identifying a relative element of indicia on the strip of corresponding indicia inside of the device identical to said exposed particular element of indicia on said slide member;
• providing a window opening in the front panel of the device through which the corresponding indicia and the indicator can be viewed;
• providing the device with a closure means for initially closing said window opening;
• handing the device to a number of persons equal to the number of slide members;
• asking each person to make a particular evaluation by pulling out a slide member until a number representing that persons evaluation appears immediately outwardly of the edge of the card-like body, and then tearing off the projecting portion of the slide member at the edge of the body, to in that manner conceal the evaluation;
• and
• delivering the device to a person who will collect the several evaluations, by opening the closure means to expose the positions of the several indictor means inside of the card-like body relative to the strips of information within the body.
