Abstract: In a preferred embodiment, there is provided an elongated tubular label holder having a contact adhesive backing by diagonally extending adhesive strips relative to a longitudinal axis of the elongated tubular label holder, the adhesive coatings extending over a major proportion of the width of the tubular label holder whereby, relative to total area of the rearward face of the tubular label holder upper and lower width-edges are firmly securable along the elongated length of the tubular label holder; the adhesive strips are spaced-apart and define diagonal spaces which provide cut-lines (imaginary) for the cutting thereof when the data insert card is in a withdrawn state; the data insert card is provided or cut with a full portion which when in the inserted state extends beyond the diagonally-cut open-end edge of the elongated tubular label holder as a handle-grasping area.

Abstract: In a preferred embodiment, an upright divider and support element is provided by an elongated wire backing having attached to the top wire a metal index tab adapted to carry a securely-held insert for noting data thereon pertaining to whatever is stored in various folders or files supported by the elongated wire backing which wire backing has an integral and continuous wire base forming centrally thereof and spaced-away from the upright divider and support element, a wire portion forming a downwardly-extending U-shaped structure which is inserted through an opening in a base plate structure, and locked when inserted through the opening, by a pin key or pin locking-element inserted through the U-shaped structure beneath the underside of the plate structure.
