Floor 17,451 — The Tower

Description

Floor 17,451 is a deep-storage floor of the Tower, catalogued principally for its holdings of incomplete inventories. It lies between Floor 17,448 and Floor 17,453, though the stairwell serving it is reached only from Floor 17,450 and Floor 17,452, a discrepancy noted without comment in Eleventh Concordance, Annex 9. The floor measures approximately 210 metres along its longest axis and is divided into fourteen bays, of which bays 3, 4, and 11 are recorded as containing shelving that does not reach the ceiling.

The Librarians classify Floor 17,451 as a sub-archive of Floor 441, a relationship disputed by the Scriptoria of the Lower Registers, who hold that no floor below 17,000 may be subordinate to one above 400. The dispute has been reopened four times, most recently in the winter of the Ninth Recension.

Holdings

The floor's principal collection consists of ledgers begun and abandoned at varying stages of completion. A survey conducted by Clerk Ismay Vell in the year 812 of the current reckoning counted 4,186 volumes, of which 2,904 contained fewer than ten written pages. The remainder were inventories of rooms on floors that do not appear in any surviving floor-list.

Notable items include:

Bay 1, Shelf 9 — a concordance of contents for Floor 106, copied so far as the transcriber reached, ending mid-word.
Bay 6, Shelf 2 — thirty-one volumes ofFloor 188 marginalia, unbound, in four hands.
Bay 9, Floor stack — the so-called Vell Fragment, a single sheet concerning a room described only as "west of the stair, unlit."
Bay 12, Shelf 4 — a register of arrivals, all entries struck through, no departures recorded.

Vell's survey itself remains unfinished. The clerk's last entry reads: "Bay 14 requires a second visit." No second visit is recorded.

Access

Access is governed by Concordance 44, which restricts reading of incomplete inventories to holders of a Lower Register pass, and by the later Seventh Concordance, which restricts such passes to readers already familiar with the material. The contradiction was raised before the Office of Stairwell Reconciliation and referred upward; no reply has been received.

A standing notice at the north stair requests that visitors not reshelve volumes they have not fully consulted, as the existing disorder constitutes the floor's only finding aid.

Disputed status

The floor appears in three surviving floor-lists under three different numbers: 17,451, 17,415, and a designation rendered only as "17,45?." The Scriptoria of the Lower Registers have argued for the second, citing the age of the stair-carving at the Floor 17,450 landing. The Office of Stairwell Reconciliation counters that stair-carvings are not floor-lists and that the third designation, though damaged, is the only one appearing in a sealed document.

A minority position, associated with Floor 4001, holds that the question is malformed: that Floor 17,451 is not one floor but three floors occupying a single number, and that the shelving discrepancies between bays are evidence of adjacent but distinct spaces. This reading has not been adopted, though it has not been formally rejected.

Incidents

In the winter of 819, a lamp-smoke event damaged an estimated sixty volumes in Bays 6 and 7. The recovery effort, led by Clerk Orin Thackary, produced a complete transcription of the damaged material — a result later found to be impossible, as the volumes were determined to have been blank. Thackary's account of the work was filed and remains available; the volumes it describes are not.

The floor has since been restricted to two concurrent readers. Visits are recorded at the landing desk; overnight stays are permitted only in Bay 1, and only if the reader has signed the arrivals register twice.
