1. A computer-implemented method for enabling a user to browse information, the method comprising:

  • storing a plurality of attribute-value pairs associated with a collection of materials, wherein each of a plurality of values has an association with at least one of a plurality of attributes characterizing the materials;

    displaying a free-text search box;

    accepting a search term entered in the free-text search box;

    determining the attribute-value pairs that match the search term;

    displaying a representation of the matching attribute-value pairs for the search term;

    accepting a selection of an initial set of one or more of the matching attribute-value pairs;

    entering a first navigation state corresponding to a first set of attribute-value pairs including at least the initial set of matching attribute-value pairs and to a first particular subset of the materials, the first particular subset of the materials consisting of those materials in the collection of materials that are each described by every attribute-value pair in the first set of attribute-value pairs; and

    entering a second navigation state in response to a user action, the second navigation state corresponding to a second set of attribute-value pairs and to a second particular subset of the materials, the second set including at least two mutually incomparable attribute-value pairs, the second particular subset of the materials consisting of those materials in the collection of materials that are each described by every attribute-value pair in the second set of attribute-value pairs.
