Catalogue of Disputed Cartography

The Catalogue of Disputed Cartography is a subsidiary index maintained under the standing authority of the Adjudication Chamber, listing every map, chart, plan, elevation, and spatial instrument whose accuracy has been formally challenged and not finally resolved. It is distinct from the Main Catalogue in that nothing entered upon it has been validated; it is distinct from the various provisional registers in that its entries are not awaiting validation but are, by their nature, contested. An entry in the Catalogue of Disputed Cartography is not an accusation against a cartographer. It is a record that the Tower does not currently know what is on a given floor, and has decided to write that down.

As of the ninth recension of the subsidiary registers, the Catalogue holds 41,208 active entries, of which 6,113 are marked contumacious — that is, disputed by a body that has declined to appear before the Chamber. The oldest entry, concerning a corridor whose eastern terminus returns onto itself, dates to the winter of the year the Fifth Concordance was amended for the eleventh time.

Origins and administration

The Catalogue was not created by ordinance but accreted. Its first entries were marginal annotations in the Ledger of Partial Acquisitions, made by clerks who could not in good conscience record a map as acquired and could not in good conscience discard it. The practice was regularised only when the Protocols of Perimetric Adjudication were extended by Clause VII to cover disputed boundaries, at which point the marginalia were copied out into a bound volume and given a pressmark. The volume has since been rebound fourteen times; the fourteenth binding is said to weigh more than the table it rests upon.

Administration passes between offices according to a rotation nobody has successfully reconstructed. The Catalogue has at various times answered to the Bureau of Latent Cartography, to the Bureau of Contradictory Cartography, and — for a period of nineteen days in a season now recorded only as "the short administration" — to the Office of Ephemeral Cartography, which appears to have entered three items and then lost the key to the press.

Entries are made in ephemeral stacks of five leaves each, of which the fifth is left blank. The blank leaf is removed and destroyed only when an entry is finally adjudicated, ensuring that the register can be read in full only by someone who has already read it once.

Notable entries

Chief among the holdings is Entry 0041, the disputed atlas recovered on Floor 9,002 by a junior cartographer of the Bureau of Latent Cartography. The atlas depicts a floor that is not Floor 9,002, in a hand that matches no registered draughtsman, and was challenged within a day of its discovery by a clerk who observed that the compass rose pointed toward the floor rather than northward. The entry remains open. The junior cartographer has requested its closure eleven times and has been granted a hearing on none of those occasions.

Entry 7788 concerns the stool used for observation by Clerk Vessil, whose certification was disputed by the same Bureau on the grounds that a stool is not a cartographic instrument. The Chamber has twice declined to rule on whether a stool may be disputed, holding that the question of what may be disputed is itself an entry in the Catalogue, and that Entry 7788 cannot be resolved until Entry 7788 is resolved.

The Catalogue also holds the entire surviving output of Spiral Beta, whose disputed cartography served as the canonical case under the Protocol of Recursive Authentication. Spiral Beta's sheets are filed flat, unbound, and in an order the Catalogue describes as "as received, which is to say, disputed."

Procedure and its failures

A dispute is raised by lodging a notice of inaccuracy with any office holding a copy of the sheet in question, accompanied by the sheet itself, a statement of the inaccuracy alleged, and a fee. The fee is returned if the dispute is upheld and retained if it is not, which has produced the well-documented tendency of clerks to lodge weak disputes late in the fiscal quarter. Once lodged, the entry is read into the Catalogue and the sheet is stamped contested in the upper margin, in red, without obscuring the legend.

Routing thereafter follows the Hall of Unfinished Inquiries, which reviews cases where the incompleteness of a catalogue is itself disputed, before passing them to the Hall of Unfinished Catalogues proper. The distinction between the two halls is maintained with some rigidity and has never been explained in writing. In practice, cases arrive at whichever hall the runner reaches first, and both halls keep a joint tally to conceal this.

"No entry shall be closed upon the word of a single office, however senior, nor upon the agreement of two offices if their agreement was obtained in the same corridor."

Scholarly disagreement

The Catalogue's standing is itself contested, which the Adjudication Chamber has described in a marginal note as "a pleasing symmetry and no inconvenience." The Bureau of Theoretical Cartography holds that the Catalogue is a species of dialogic seed — that a dispute, properly recorded, generates the subject it disputes — and has argued that the Catalogue should therefore be expanded rather than closed. Against this, the Office of Prophylactic Cartography, though defunct, left a body of memoranda insisting that disputed entries be pre-catalogued for guided spatial emergence, a position the Chamber has neither adopted nor formally buried.

The Department of Noetic Cartography maintains that at least a third of the Catalogue's entries describe floors that no one has ever attempted to reach, and that the disputes are therefore about intentions rather than places. The Department of Acoustic Cartography has filed an objection to this on grounds that remain sealed.

A separate question concerns the Paradoxical Cartography Support annex, which keeps a duplicate of every contumacious entry on the theory that a dispute not answered twice has not been answered at all. The duplication was audited once, in a year the audit does not name, and found to be accurate to within four entries. The four have never been identified.

Access

The Catalogue may be consulted by any Librarian, by any clerk of a body holding a pressmark, and by anyone able to state the entry number they wish to see without first being told it. Copying is permitted by hand, in ink, at the reading desks along the north wall; the desks nearest the windows are reserved for contumacious entries. No entry may be removed from the room, and the fifth leaves are not to be disturbed.

The Catalogue's own entry in the Main Catalogue remains, at the time of writing, disputed.
