Ted Nelson's PhD thesis, 2002, with emphasis on philosophy of description and connection. Nelson sees everything as connected; writing is the difficult process of subtraction and sequentializing. Nelson argues that parallel, connected pages are the most general form of writing. This combines both sequence (on the page) and connection (between pages). Parallel pages offer many variations and possibilities, and can best represent not only such historic connections as the Talmud, the Rosetta Stone, but history itself.
