    Abstract: A three ring binder includes a spine, a front cover and a back cover, each of which includes a substantially solid base plate and an outer plastic shell. The front cover and spine may each include a front cover pocket and a spine pocket, respectively. A tab assembly is slideably mounted within at least the front cover pocket, and the pocket is formed from a transparent plastic sheet such that the tab assembly is viewable through the transparent sheet. The tab assembly may include a support sheet and display sheet. The display sheet may be any type of information or display material as long as it is dimensionally smaller than the support sheet. The support sheet is dimensionally slightly smaller than the pocket so that it can be slidingly inserted into the pocket.
