Linking, made possible by a unique and immutable number, solves the problem of multiple storage (2:29) in "a paper-based hypertext" way, Sascha2020 and also enriches the content of the notes, since "every note is only an element which receives its quality only from the network of links and back-links within the system". (2:52) Put it another way, to prevent a slip getting ill and turning into an orphan, 0b1a "we must seek internal possibilities for linkings which result in the unexpected (i.e. information)", (3:17) "at the occasion of writing notes or making queries" (3:20).

²⁷Since all papers have fixed numbers, you can add as many references to them as you may want. ²⁸Central concepts can have many links which show on which other contexts we can find materials relevant for them. ²⁹Through references, we can, without too work or paper, solve the problem of multiple storage. ³⁰Given this technique, it is less important where we place a new note. ³¹If there are several possibilities, we can solve the problem as we wish and just record the connection by a link [or reference].
