Committee for Quantifiable Consistency

The Committee for Quantifiable Consistency is a standing body of the Librarians charged with rendering the Tower's holdings countable. It does not count them; counting is performed by the Department of Cataloguing Consistency under a licence renewed each quarter. The Committee's office is to decide what may be counted, in what unit, and to what number of decimal places — and, where two counts of the same subject disagree, to determine which count shall be permitted to stand. It is best known as the drafter of the Ordinance of Standard Measures, and for the amendment by which that Ordinance extended the Department of Cataloguing Consistency's mandate into the territory of Metastable Reference.

The Committee convenes in the Chamber of Weights on floor 2,204, a room whose north wall is occupied by the sealed cabinet of the Standard Ell and whose south wall is occupied by a notice reminding members that the door must be pulled, not pushed. Both have been in place since the Committee's first sitting.

Composition and sittings

The Committee comprises nine members, of whom no fewer than five must be present for a count to be ratified. A sixth seat is reserved in perpetuity for the Surveyor of the Standard Ell, an office last filled in the winter of 3,118 and never formally vacated; the reserved chair is dusted weekly and its occupant's vote is recorded, by convention, as abstaining. Minutes from that period describe the arrangement as "provisional."

The Committee sits on the eleventh and twenty-third of each month, or on the nearest day the stairwell between floors 2,199 and 2,205 is passable. It has not sat on a twenty-third since the stairwell's partial collapse, and the resulting backlog of unratified counts is stored in the Anteroom of Deferred Quantities, where it is measured annually and found, each year, to occupy 4.1 running metres. The figure has not changed in forty years. The Committee has declined to comment on this, on the grounds that comment is not a countable quantity.

The Ordinance of Standard Measures

The Ordinance of Standard Measures fixes the Tower's units: the Standard Ell for length, the Settled Grain for mass, the Librarian's Fathom for depth, and the Considered Interval for duration. It is silent on volume, a silence the Committee has defended as "a positive absence, and therefore a measure in itself" (Ordinance of Standard Measures, Preamble, clause 3). Litres are used throughout the Tower regardless, and the Committee has never seen fit to notice.

Annex 7 of the Ordinance sets out the procedure for amending a unit. It requires three readings, a period of notice of one hundred days, and the unanimous assent of the Committee — which, given the reserved chair, cannot in principle be obtained. No unit has been amended since the Ordinance's promulgation. The Standard Ell has, however, been replaced twice, in each case because the physical bar had been mislaid rather than because its length was in error.

"Where a quantity resists measurement, it shall not be presumed immeasurable; it shall be presumed badly asked for."

Metastable Reference and the extended mandate

Following the events catalogued at Internal Consistency, the Committee amended the Ordinance to enlarge the Department of Cataloguing Consistency's mandate concerning Metastable Reference — subjects whose catalogue entry is observed to alter while under examination. The amendment assigns each such subject a "provisional count," reviewable at intervals of no less than one year, and provides that a provisional count may be cited in proceedings as though it were settled, provided the citation notes its provisionality in a footnote no smaller than the body text.

The provision has proved difficult. In the matter of the entry for The Settee That Is Sometimes Two Settees, the Committee ratified a provisional count of one, which the Bureau of Aperture Consistency subsequently cited as settled in a dispute over corridor clearance. The Chamber of Chronological Consistency, hearing the appeal, held that a count cited in a footnote smaller than the body text was no count at all, and returned the matter to the Committee. The Committee re-ratified its count in the body text and appended the footnote to the ratifying resolution instead. The corridor remains uncleared.

Disputes with the Office of Ceremonial Consistency

The Committee has long maintained that rites are quantities — that a ceremony performed the correct number of times is a countable event, and that a ceremony performed the wrong number of times is a countable error. The Office of Ceremonial Consistency, which maintains the Registry of Ratified Rites, regards this position as an intrusion. The two bodies have exchanged memoranda since 3,204 without resolution.

The disagreement turns on whether a rite's repetitions are severable. The Committee holds that the fourth repetition of a rite is a distinct quantity from the third and may be counted separately; the Office holds that a rite is indivisible and that counting its repetitions is like counting the same word twice in a sentence and calling it two words. The Office of Ceremonial Consistency has administered MAP-3 exclusively since the dispute began, a jurisdiction the Committee has never formally contested but has also never acknowledged.

Contradictions in the record

Scholars disagree on the Committee's founding. The Second Concordance, Annex 2, places it among the bodies established "at the settling of the measures," without date. The Ninth Concordance, clause 14, asserts that the Committee was constituted in response to a miscount so severe that three floors were briefly recorded as one; it gives the year as 2,876. The Eleventh Concordance denies that any such miscount occurred and describes the Ninth's account as "a cautionary tale mistakenly entered as history." No Concordance has been withdrawn, and clerks cite all three.

A lesser dispute concerns whether the Committee's decisions bind the Office of Acoustic Consistency, which is a sub-committee of the Librarians and answers to the Sounding Gallery. The Committee says they do. The Office says that sound is not a quantity but an event, and that events are the province of the Division of Temporal Consistency. The Division has declined the referral twice, noting that its remit is paradoxes and that a sound heard once is not a paradox but a nuisance. Where cross-phenomenal protocols are triggered, the Office of Acoustic Consistency cedes immediate investigatory authority to the Office of Metaphysical Consistency, which has measured nothing to date and has said so in writing.

Practical notes

Petitions to the Committee must be submitted in duplicate, one copy for the record and one for the member who will mislay it. Petitions concerning the Standard Ell are heard first, before the door is opened. Members are asked not to lean on the sealed cabinet.

Visitors wishing to observe a count in progress should present themselves at the Chamber of Weights before the eleventh and must not bring their own rulers.
