One embodiment of the present invention provides a system for determining and saving a location of a section of an item of content. During operation, the system receives a section of a content map associated with the item of content from an input device, wherein the content map is located on the same physical medium as the item of content, and wherein the section of the content map is collocated with the section of the item of content, whereby the input device can be positioned in close proximity to the section of the item of content to receive a corresponding section of the content map. The system then uses the section of the content map to determine the location of the section of the item of content. Then, the system saves the location of the section of the item of content at the client. Note that saving the location of the section of the item of content facilitates subsequently retrieving the section of the item of content.
