Fable
Two numbering methods in the archive
The archive wanted apprentices to quickly look up old cases. At first the whole volume was too thick—finding a single testimony took half a day. So the curator had the files cut into small pieces, each labeled with a number, and lookup became much faster. The apprentice was like taking small pieces from a large platter—easier to swallow.
Trouble followed. An apprentice found a sentence saying "the riverbank has been repaired," but did not know which year, which stretch of river, or who had inspected it. Small pieces are like cut tofu: easy to swallow, but they lose the flavor of the original dish. A fragment looks accurate, but only when put back into the original case does one realize the meaning has changed.
Someone suggested cutting the slices larger. Larger gives enough context, but lookup is slow; smaller gives accurate lookup, but reading is fragmented. The two sides argued for days without resolving it. The first fix just went in circles around the blade thickness and didn't address the relationship between the small slices and the original scroll.
The old librarian switched to parent-child volumes. Small pieces were still used to find clues, like touching a key piece of testimony in a catalog; once a hit was found, the large page or entire parent volume it belonged to was pulled out together, letting the apprentice judge within the original context.
The first version of the father-son volume also had problems. If the father volume took too much, the desk was again piled with paper; if the father volume took too little, the causes and consequences were still unclear. The old librarian redefined the scope by case: testimony included interrogation pages, engineering records included the acceptance sections before and after, and accounts included the same batch of income and expenditure.
Later the archive had two rulers: how fine the small pieces were determined how accurately you could find things; how large the parent volume was determined whether what you retrieved was complete enough to read. Apprentices first used the small pieces to locate, then relied on the parent volume to understand, no longer treating a single isolated sentence as the conclusion of an entire case.
Cutting it into pieces is only finding the needle; bringing the parent volume back too is how you know what garment the needle was stuck in. What the archive truly learned was not to cut more finely, but that searching and understanding are two separate steps.
Later, when new cases entered the archive, the archivist first decided two things: how small a piece to use for the index, and how large a parent volume to provide for reading. The former affected whether something could be found; the latter affected whether it could be judged. Once the two rulers were clearly separated, the files were no longer cut into amnesiac scraps. Later, when archivists looked up a short phrase, they would first ask which volume it belonged to, then decide whether it could be cited.
