    • III: Display dependencies for Tree-Structured Spatial Hypertext Blake cannot become the child of Swedenborg if it is Swedenborg’s parent Comparing Spatial Hypertext Collections Hypertext 2009 J. Nathan Matias & David Williams
    • III: Display dependencies for Tree-Structured Spatial Hypertext Blake cannot become the child of Swedenborg if it is Swedenborg’s parent Something else must become the parent of Swedenborg for Blake to become its child. Comparing Spatial Hypertext Collections Hypertext 2009 J. Nathan Matias & David Williams
    • III: Display dependencies for Tree-Structured Spatial Hypertext Blake cannot become the The movement of Blake child of Swedenborg if it to Swedenborg is Swedenborg’s parent depends on Tennyson becoming the parent of Something else must Swedenborg become the parent of Swedenborg for Blake to become its child.
