1. Regesten Da wir gesehen haben, wieviel auf tibersichtliche Ordnung bei der Zusammenstellung des Materials ankommt, muß man auf die praktische Einrichtung seiner Materialiensammlung von Anfang an bewußte Sorgfalt verwenden. Selbstverständlich lassen sich keine, im einzelnen durchweg gültigen Regeln aufstellen; aber wir können uns doch über einige allgemeine Gesichtspunkte verständigen. Nicht genug zu warnen ist vor einem regel- und ordnungslosen Anhäufen und Durcheinanderschreiben der Materialien; denn die zueinander gehörigen Daten zusammenzufinden erfordert dann ein stets erneutes Durchsehen des ganzen Materials; auch ist es dann kaum möglich, neu hinzukommende Daten an der gehörigen Stelle einzureihen. Bei irgend größeren Arbeiten muß man seine Aufzeichnungen auf einzelne lose Blätter machen, die leicht umzuordnen und denen ohne Umstände Blätter mit neuen Daten einzufügen sind. Macht man sachliche Kategorieen, so sind die zu einer Kategorie gehörigen Blätter in Umschlägen oder besser noch in Kästen getrennt zu halten; innerhalb derselben kann man chronologisch oder sachlich alphabetisch nach gewissen Schlagwörtern ordnen.

1. Regesture Since we have seen how much importance is placed on clear order in the gathering of material, conscious care must be exercised in the practical organization of one's collection of materials from the outset. It goes without saying that no rules that are consistently valid in detail can be set up; but we can still agree on some general points of view. There is not enough warning against a disorderly accumulation and jumble of materials; because to find the data that belong together then requires a constant re-examination of the entire material; it is also then hardly possible to line up newly added data at the appropriate place. In any large work one must make one's notes on separate loose sheets, which can easily be rearranged, and sheets of new data easily inserted. If you make factual categories, the sheets belonging to a category should be kept separate in covers or, better yet, in boxes; Within these, you can sort them chronologically or alphabetically according to certain keywords.

In a pre-digital era, Ernst Bernheim warns against "a disorderly accumulation and jumble of materials" (machine translation from German) as it means that one must read through and re-examine all their collected materials to find or make sense of them again.

In digital contexts, things are vaguely better as the result of better search through a corpus, but it's still better practice to have things with some additional level of order to prevent the creation of a "scrap heap".

In 1889, Bernheim suggests making one's notes on separate loose sheets of paper so that they may be easily rearranged and new notes inserted. He suggested assigning notes to categories and keeping them separated, preferably in boxes. Then one might sort them in a variety of different ways, specifically highlighting both chronological and alphabetical order based on keywords.

(This quote is from the 1903 edition, but presumably is similar or the same in 1889, but double check this before publishing.)

Link this to the earlier section in which he suggested a variety of note orders for historical methods as well as for the potential creation of insight into one's work.
