Abstract: A checkbook comprising alternate check blanks and check stubs with the check stubs being treated with pressure-sensitive material so that when a check is drawn the information placed on the check will also be reproduced on the check stub. The checks are attached at the left-hand edge to a cover and to a backing material which extends beyond the right-hand edge of the check blanks a distance approximately equal to the width of the check blanks and is creased and may be inserted between the check stub and the check blank thereunder so as to prevent writing from appearing on other check stubs thereunder. The backing material also functions as a check register for specific checks if so desired, as well as deposit and other information. The check stub has positioned on it indicia so that the numeric expression of the amount of the check will appear in a column on the stub immediately below the balance forward so that amount then may be deducted from the balance forward to produce a balance.
