An expandable outside pocket (60) is provided on one panel of a binder (50). This pocket includes a releasable closure to control expansion of the pocket . In one configuration, the outside pocket includes a zippered gusset (70), where the zipper (72) can be closed to prevent expansion of the pocket capacity. The gusset (70) and zipper (72) configuration enables the pocket t o be expanded when it is desired to increase the size of the pocket in order t o accommodate larger items such as books, but also enables the gusset to be he ld in a non-extendable position when the pocket does not need to be expanded, such as when the pocket is only used to carry papers or slim folders. A seco nd zipper (78) is preferably also provided in order to control access to the pocket. In another configuration, the outside pocket includes gussets along its sides which facilitate expansion of the pocket, and a single zipper provides access to the pocket interior when unzipped and also enables the pocket to expand when unzipped. The pocket can be expanded to provide simple access to the pocket interior, permitting convenient perusal of papers withi n the pocket without removal of the papers.
