A binder, such as a three ring binder, is provided with a read/write panel on the front cover of the binder and with a stylus mounted onto the binder. The read/write panel may be inset into the cover of the binder, or it may constitute substantially the entire front cover of the binder, or it may be inserted into a transparent pocket on the front cover of the binder. The read/write panel includes inner and outer sheets with material between the sheets forming an image upon appliction of a stylus. In one embodiment the inner sheet may be coated with a waxy material; and in another embodiment magnetic particles in a viscous medium are employed. For the magnetic embodiment, the eraser may be of a broad area permanent magnet type which may be brought into engagement with the entire magnetizable panel; or a smaller linear permanently magnetized eraser may be employed. The binder preferably is a full size binder for 8 ½x11 inch or A-4 size sheets of paper.
