    Abstract: A method and system for providing location-based information to a mobile or fixed subscriber. A subscriber requests information through an information manager which maintains a location-indexed database (L-database) containing web servers addresses of entities hosting information of interest to the subscriber. The subscriber requests the information through a handheld device ( wireless phone or PDA) or through a desktop or laptop PC. The information manager receives also the subscriber's current location information in terms of street address or geo-location and queries the L-database to identify entities hosting the requested information. The information is then retrieved directly from the identified servers and presented to the subscriber in a format suitable to the subscriber device.
