Claim:
A method of retrieving a document from a database of hierarchical electronic document versions, each document version being associated with a unique document instance, the method comprising the steps of: printing a search form, the search form including a search instruction input field relating to at least one parameter of a search to be carried out within the database and a plurality of coded data tags, each coded data tag encoding a location of that coded data tag on the search form; sensing the coded data tags by a sensing device as the sensing device is used to handwrite at least one search term on the search form; generating data representing the parameter and the at least one search term, the data representing the at least one search term being generated from the locations of the coded data tags; carrying out a search within the database based on the at least one search term and parameter in order to identify document versions; printing a results form, the results form containing data representing the document versions identified in the search and coded data tags; sensing one or more coded data tags on the results form; retrieving the document version associated with the coded data tag sensed on the results form; and printing the document version associated with the coded data tag sensed on the results form.
