An information system includes a server that creates an information reservoir with data units for a user of a mobile communication device based on a unique user profile of the user of the mobile communication device. The server creates the unique user profile based on interaction of the user with the mobile communication device or with another computing system. The server transfers the information reservoir to the mobile communication device and each time the user requests data from a web site, the server scans it to find key terms. If the server finds key term(s) in the data, it uses a tagging rule to mark the key term(s) and, then, it transfers the data with the marked term(s) to the mobile communication device. The user may, then, select a marked key term to call/display a data unit that is locally stored on the mobile communication device. The server may also mark terms in data units and a data unit stored on the mobile communication device may be called using a key term that is marked in another data unit.
