ABSTRACT:
A system and method for retrieving the contents of a digital information system by multi-level categorization is disclosed. The system uses a file table, a category table, and a category bundling table. Headings and directions are displayed on navigation pages to guide the user to the desired file. The description and hierarchy relationship of categories, sub-categories, and files are stored in the tables. When the user selects a category or file and the direction of navigation, the system returns the file, or consults the tables and returns a list of new categories and files for a new navigation page. Moving down and then up through a category usually produces a different navigation page. Dynamic updating of the system categories and files can be easily accomplished by altering the content of the tables.
