Methods for searching relationships between and among documents are detailed. One method includes steps for selecting one or more initial search items from a group consisting of: (a) document objects, (b) link references to document objects, (c) link reference attributes, and (d) link relationship attributes. The method also includes steps for identifying one or more link relationships using the selected initial search items, and for presenting one or more link relationships attributes describing the identified link relationships. A user interface for presenting and searching relationships between document objects located on a network is also detailed. The user interface may include a first portion of a screen display for displaying one or more link relationship attributes and a second portion of the screen display for displaying one or more entries from a group consisting of: (a) link references that represent the document objects, (b) link relationship attributes describing the link relationships, (c) link reference attributes describing the link references, and (d) document objects. The displayed entries in the second portion of the user interface are related to the displayed one or more link relationship attributes in the first portion.
