§ 03 of 05 — Stage Three · Classify
Where does it sit in human knowledge?
A cluster is named. A person has been told apart from their namesakes. Now: where does the book they wrote sit? Dewey gives one number. FAST gives many access points. The difference between them is the difference between a tree and a graph — between hierarchy and intersection — and it is one of the oldest live debates in cataloging. This room sets them next to each other for the same book.

Dewey — one number, one path
Dewey is a hierarchical scheme: every book belongs at exactly one number, and that number is the leaf of a single descending chain from 000 through narrower and narrower categories. Click each level to see what it does and why it is shaped the way it is — Dewey's idiosyncrasies are part of the lesson.
one location in the tree
- Postwar through end-of-century. King's entire active publishing life sits here. The 21st-century portion of his career has begun to spill into 813.6.
FAST — many headings, an intersection
FAST takes the opposite stance. The same book carries many independent access points across separate facets — topical, geographic, chronological, form. The book does not sit in any single place; it sits at the intersection of all of them. Click any heading to see what it tells the catalog.
an intersection in the graph
Click a heading to see what it does — and doesn't — tell the catalog.
A book in FAST is not in one place — it is at the intersection of all its access points. Two visitors looking for it will arrive from different directions: one looking for horror tales, one looking for Maine, one looking for novels about children. Each path is a real way the catalog can find the book.
What this page actually does, and what it doesn't.
- An interactive Dewey tree showing the actual hierarchical path from 800 → 813.54 for a real published book, with editorial notes on why each level exists.
- FAST headings grouped by facet (Topical, Geographic, Chronological, Form/Genre), each with a per-heading note on what that access point tells the catalog.
- Side-by-side framing that lets the visitor feel the difference between 'one number' and 'many headings' for the same work.
- That Dewey and FAST are direct competitors. They are; but most large library catalogs run both simultaneously — Dewey for shelf order, FAST for subject access — and treat them as different tools for different jobs.
- That the Dewey path is the only possible classification for this book. A cataloger looking at King's *It* could legitimately have placed it at 813.6 (post-2000) or with an additional subject number; the chosen path is the most common one in WorldCat.
- That the FAST headings shown are exhaustive. Real WorldCat records for this title carry additional headings; we showed the most pedagogically clear six.
- The Dewey editorial notes per level are written for legibility, not transcribed from the DDC tables. The numeric breakdown is accurate; the prose framing is ours.
- The 'siblings at this level' list is a representative subset, not an exhaustive enumeration of every Dewey number adjacent to 813.54.
- FAST IDs are illustrative formatting; some IDs in real FAST are longer or carry version suffixes. The point is the shape of the controlled vocabulary, not the exact identifier syntax.
Classification is an epistemology, dressed as a notation.
The reason Dewey and FAST cannot be reconciled by a converter is that they disagree about what knowledge looks like. Dewey is a tree: knowledge has a single root, descends into nine main classes, divides cleanly into ten subclasses each, and admits exactly one location per book. FAST is a graph: a book is described by independent dimensions, and the dimensions intersect rather than nest.
The tree is older — Melvil Dewey published the first edition in 1876, eight decades before the postcoordinate-indexing schemes that would eventually become FAST. The tree has the advantage of being walkable: you can stand at any node and look up at the parent. The graph has the advantage of being queryable: you can intersect facets and arrive at any book by any of its access points.
Modern software-shaped intuition tends to pick FAST as the obvious winner. The graph is more flexible; the tree is brittle. But the tree is what makes a physical library navigable — it is what decides which book sits next to which other book on the shelf — and the act of having to choose one location is itself a forcing function on the cataloger's thinking. Forced single placement makes you decide, even when the work resists.
Once a work has been classified, it is locatable — by topic, by place, by genre, by anything else the cataloger has thought to name. But the catalog has not yet said what the work touches. Stage 4 walks outward. From this one work to its author. From the author to her contemporaries. From the contemporaries to their shared subjects. The graph that FAST hinted at becomes the room you stand in.
Stage Four · Connect — what does it touch?
FAST already implied the answer: each facet is a path into a larger graph. Stage 4 walks that graph — works by, works about, influences, contemporaries, subjects in common — and asks what you can see only when identity is connected, not just named.
