A rotatable binder insert for supporting and holding such articles as calculators or other electronic devices, to-do lists and check lists, self-stick removable notes, etc., that are used to supplement, or in conjunction with, information written on the pages of the binder. Inasmuch as such information may be found on both sides of the binder rings, i.e., on both right- and left-hand pages, an article used therewith must similarly be visible and accessible on alternate sides of the binder rings. By being mounted on a support member capable of rotating 180 DEG on a frame insertable anywhere in the binder and readily attachable to the binder rings such articles can be placed alongside information found on either right or left-hand pages.
