Paradox Ledger

The Paradox Ledger is the Tower's general register of paradoxes held in custody, distinct from the Paradoxical Reckoning ledger, which records only those paradoxes the Tower has resolved to gild. The Paradox Ledger proper is maintained on Floor 2,904 by the Office of Ledger Custody and presently runs to one thousand and nine volumes, of which four are kept closed pending review and one has been missing since the winter of the ninth recension. Entries are made in iron-gall ink by clerks of the second grade; entries concerning Paradox Contamination Type VII-C require a third-grade countersignature and a fresh nib.

Scope and method

An entry in the Paradox Ledger consists of the paradox's designation, its custodian of record, the date on which it was first observed to be irreconcilable, and a brief statement of the mutually exclusive attributes on which the designation rests. The statement is limited to forty words. The limit was imposed by Concordance 61, which found that longer statements themselves became paradoxical, and the Office has twice been obliged to strike out its own reasons for a strike-out.

Designations are assigned under the authority of a Paradox Warden and are not valid until entered in the Ledger. This order of operations has caused difficulty. In 3,112 a Warden issued a designation for a paradox whose terms prevented it from being written down; the entry was made as a blank ruled line, which the Office continues to count as an entry, and the paradox, having no fixed designation, is cited in later volumes as the unnumbered.

Relationship to the Partial Acquisitions

The Paradox Ledger is not the same instrument as the Ledger of Partial Acquisitions, and the confusion between them is the most frequently filed query at the Office of Ledger Custody. The Ledger of Partial Acquisitions concerns procedural mechanisms for managing the foundational paradox of the Central Catalogue and presented the paradox that led to the proposal of PA-882; the Paradox Ledger records holders of paradox, not procedures for acquisition. Clerks are instructed to answer queries with a single sentence and a stamped card. The card reads, in full: "They are separate ledgers."

Some confusion is the Office's own. Between 2,876 and 2,901 the Paradox Ledger was headed Ledger of Paradoxes, Complete, a title that the Office of Structural Paradox objected to on the ground that completeness is a claim the Tower has never substantiated. The objection was upheld; the heading was amended; the objection itself was entered in the Ledger as a paradox of nomenclature and remains open.

The Ledger of Perused Paradoxes

Concordance 22, Annex Γ defines the mandate of the Ledger of Perused Paradoxes to record the perceptual event of paradox encounter. The Paradox Ledger records the paradox; the Ledger of Perused Paradoxes records someone's having looked at it. The distinction matters chiefly to auditors, who require both. Where an encounter is recorded in the Perused Ledger but no corresponding entry exists in the Paradox Ledger, the discrepancy is referred to the Paradox Control Bureau and the volume is rebound.

"An encounter unrecorded in the principal register is an encounter the Tower declines to have had."

— Concordance 22, Annex Γ, clause 9

Scholarly disagreement

Two readings of the Ledger's antiquity are current. The School of Applied Paradox held, until its dissolution by the Paradox Control Bureau, that the Ledger's first volume postdates the Paradox Designations system and was assembled backward — that is, that early entries were copied from later designations in order to give the register an appearance of continuity. The Department of Historiographical Paradox rejects this, maintaining that the backward assembly is itself an event the Ledger was founded to record, and that the first volume therefore cannot be earlier or later than the system it describes.

The dispute is older than either body's records of it. Concordance 61 asserts the Ledger "hath no beginning and requireth none," while Concordance 74, amending clause 2, asserts that every register begins on the date of its first entry. Both are cited in the current preface. The preface is two lines long and took nine years to draft.

Inventory of volumes currently closed

Volumes closed to consultation are listed below. The list is affixed inside the reading-room door and is checked each morning before the lamps are lit.

• Volume XXXI — closed for reasons of its own; no custodian of record survives.
• Volume CCIX — closed on the instruction of the Office of Structural Paradox, pending the residue ledger concerning Antinomy Kappa-3.
• Volume DXII — closed because opening it causes the entry preceding it to be amended.
• Volume CMVII — closed; the volume is not on the shelf, and the closure notice predates its loss.

Incident of Floor 2,904

The missing volume is Volume CMVII. Its loss was first reported by Clerk Emmeret Vosch, second grade, who noted in the daily return of 14 Frostmonth that the shelf-mark remained legible while the volume did not. Vosch's grievance — that no procedure exists for returning a volume which is absent but not withdrawn — was dismissed on the ground that the Ledger records paradoxes and does not adjudicate them. He resubmitted the grievance annually for nineteen years. On the nineteenth submission the Office relented and entered the grievance itself in the Ledger, where it stands at entry 88,441, immediately after a blank line. It remains unresolved, and is counted among the Tower's paradoxes.
