A thin flexible cover is fitted over the item-retaining housing in a conventional ring binder. The cover may be adhered, snap-fitted, or permanently attached, e.g., by riveting, to the underlying housing portion. A visible surface of the cover is provided with information relating to items to be retained in the ring binder by symbols, letters, numerals or the like in different colors, textures or even in Braille to meet the needs of a sight-impaired user. The item-related information thus provided is accessible to the user when the ring binder is in its open stste and contains retained items on one or both sides of the central housing. By suitable choice of thickness and stiffness of the cover material, the cover can be used to enhance the item-retaining function of the ring binder. The cover, in all of its embodiments, also serves to protect retained items from damage due to scratching, denting, or rusting/corrosion of metal elements of the item-retaining housing over time. In various aspects, the cover may be applied to the housing either permanently or removably, either when the ring binder is manufactured or subsequently.
