There are two ways for a communication system to maintain its integrity over long periods of time: you need to decide for either highly technical specialisation, or for a setup that incorporates coincidence and ad hoc generated information. Translated to note collections: you can choose a setup categorized by topics, or an open one. We chose the latter and, after 26 successful years with only occasionally difficult teamwork, we can report that this way is successful – or at least possible.

We were naturally at first rather puzzled to account for thisbox. Were its contents an accidental collection of left-overs?Was it a receptacle for random deposits of casual scraps ofwriting? Should the large works which were some of its sourcesbe published and it be left on one side?
