Abstract
A portable storage medium is used to store data and provide access to information from an information dissemination system (IDS). The storage medium can store one or more location/key pairs. Each of the location/key pairs designates a particular IDS location as well as an access key to the particular IDS location. The storage medium can also store a plurality of information units. The information units are categorized into levels of information categories with at least one information category per level and at least one information unit per information category. Levels of information categories can be individually accessed and categories of information units within levels can be selectively downloaded.
