A document information management system includes a database containing a plurality
of document files with raster information previously stored therein, a display
unit for displaying hypertext and non-hypertext documents, a marking pen unit,
an execution instructing unit, a marking command analyzing unit, a first and second
retrieving units, and an output unit. The marking pen unit has a marking pen for
giving at least one marking command to one or more buttons or words for a hypertext
document and one or more words in a non-hypertext document each displayed on the
display unit. The marking command analyzing unit analyzes, when instructed by the
execution instructing unit, contents of the marking command based upon the command
mark as a button or key word. The analyzing includes a displacement comparison
of the raster information. The first and second retrieval units retrieve related
hypertext or non-hypertext documents, respectively. The output unit then outputs
the related information.
