Fable
The library no longer stores only book titles, but also the context of every page
The south city library used to record only book titles and authors. When readers asked questions, the librarian first found a book, then flipped through it from beginning to end.
Later, more people came asking questions, and the questions became more specific. Some only wanted a clause on a certain page, some only looked at the latest version, and some could only view the files of their own firm. The old registry quickly became insufficient. A customer also asked to withdraw an old contract. The librarian removed the original book from the shelf but forgot the excerpts scattered in the wooden box, and days later the Q&A still cited that old clause.
The administrator first puts the excerpt slips into an ordinary wooden box. Some answers can be found, but it's impossible to tell which book, which page, which year's edition each slip came from, or who is qualified to see it.
He also stored the original text, summaries, permission badges, and update records separately. After finding a single note, he still had to piece together its source from four different places, often grabbing the wrong old version, and even handing Merchant A's materials to Merchant B.
The new curator established a dedicated library. Each fragment carried its main text, source page number, topic tags, version, update time, visibility scope, and position of adjacent paragraphs. Related fragments were also linked together by number. The first dedicated library also made mistakes: it stored only the main text, not the adjacent paragraphs. When a librarian answered a certain exception, they omitted the limiting condition in the preceding paragraph, causing another dispute.
Librarians can retrieve materials by literal text, theme, or condition. When answering, citations can accurately return to the original book; when a customer deletes a volume, the related fragments and indexes are cleared along with it.
The library still had to be maintained. Old versions going offline, new versions replacing them, permission changes, and duplicate fragments being merged all had dedicated staff checking them. Every update left a record of where the old version went. When someone asked why a certain answer had changed, the librarian could trace whether it was due to a new clause replacing the old one, tightened permissions, or fragments being merged. The head librarian also set expiration reminders for each fragment. When a certain type of contract expired or a batch of manuals was recalled, the library would prompt the librarian to review. Being able to store something is only the first step; being reliable means not continuing to misuse it after changes.
The curator finally understood that the foundation of Q&A cannot be a pile of loose papers; it must be a document library that supports search, citation, permissions, and updates.
