    Abstract: A case supports a multi-leafed notebook and a file. The notebook is supported by a pair of spaced brackets having prongs extending toward one another with a prong of each bracket inserted between leaves of the notebook. A prong on one bracket has a depending portion to prevent the notebook from escaping the prong. A stop member is movably mounted on one bracket and engages the notebook to prevent inadvertent release of the notebook. The stop member has a scalloped edge for engaging the prongs. Support pockets are disposed on the front and back parts of the case by a single sheet of material having an intermediate part sealed to the hinge of the case. A file support pocket is formed by a sheet of material having free side edges. The file has a cover member and a plurality of interior members pivotally connected to one another along fold lines.
