Abstract
The invention provides for 'windowing' leafs of various types which retain their face and perimeter orientation when repositioned with respect to their host binder, including leafs with pluralities of surfaces, leafs with arrays of stacked repositionable notes, leafs with notepads, leafs with arrays of clips, and the like. The invention further provides for the binding of leafs which themselves may be electronic modules, each acting as a means for one of capturing, storing, accessing, displaying, and transmitting information in electronic form. Further, binding system cover is provided which offers a ring binding mechanism that is simple, light weight, and of a closed loop design available in various application specific shapes. Leaves and mounting surfaces according to the invention provide semi-permanent retaining means which enable easy removal and reinsertion, permitting rapid reordering, while retaining their semi-permanent binding during the page turning operation, independent of the weight of the mounting surface, any force orthogonally inward or outward with respect to the host coupling structure, and any position it may take in turning as it twists over its coupling structure, and to book systems formed by combining covers, rings, and mounting surfaces according to this invention that offer compact, reconfigurable, highly visual means for handling heterogenous, mixed media forms of information.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
