1. A method of converting a hardcopy document to an electronic document comprising the steps of:
- scanning a hardcopy document containing encoded link information and one or more regions designated to be active associated with said encoded link information;
decoding the encoded link information to obtain the link information associated with said one or more regions;
locating said one or more regions in a scanned-in version of the hardcopy document, wherein the step of locating comprises searching a bit map of the scanned hardcopy document using a template stored in the encoded link information and obtained when decoding the encoded link information; and
creating an electronic version of the hardcopy document having said one or more regions linked to electronic information, such that selection of any of said one or more regions accesses linked electronic information.

Abstract
A conversion method and apparatus that allows for converting a hardcopy document into a hyperdocument and vice versa. During hardcopy to hyperdocument conversion, hypertext information stored on the hardcopy document is used to set up links to other documents. During hyperdocument to hardcopy document conversion, hypertext link information is encoded and stored on the hardcopy document.
