Nominal Anchors

Nominal Anchors are material, procedural, or nominal fixtures established to stabilize transient or volatile subjects within the cataloging architecture of the Tower by fixing them to a name. They are the oldest and most heavily disputed class of Conceptual Anchors, and the only class whose authority rests on a single clause of a single document — Clause 31 of the Third Concordance, "On the Naming of Ephemera," which authorized the assignment of nominal anchors to entities of indeterminate ontological stability. Nominal anchors do not hold a subject in place. They hold it to a word, and the word is expected to do the rest.

Origin and text

The Third Concordance was recensed in the winter of the year recorded as 3C-114, and Clause 31 entered it as a brief procedural permission: that ephemera lacking a stable designation might be "held to a name duly entered, and shall not thereafter drift from the entry." The clause is eleven lines long. Its commentary exceeds four hundred folios.

The clause did not create nominal anchors — the practice of pinning a wavering subject to a written name is attested at least two recensions earlier — but it made the practice lawful and, more consequentially, made the name itself the instrument rather than the label. Earlier practice had anchored ephemera with weight, thread, or enclosure. Clause 31 substituted a word for the weight, and the Librarians have argued ever since about whether this was an economy or an error.

"A nominal anchor is not a name given to a thing; it is a thing given to a name, and the name is the stronger party."

— Dissertation on Nominal Integrity, Elara of the Seventh Cadence, folio 12

Relation to other anchors

Nominal anchors sit within the wider family of Conceptual Anchors but are distinguished from the material subclasses by having no physical footprint whatsoever. A Fixed Geospatial Anchor occupies coordinates; a Material Anchor occupies matter; a nominal anchor occupies a line in a register. It is for this reason that nominal anchors are the cheapest to establish and the most expensive to withdraw. A withdrawn geospatial anchor leaves a floor. A withdrawn nominal anchor leaves a word, and the word may by then have acquired other tenants.

The subclass is frequently confused with Absence Anchors, which impose a regulated void, and with Designated Volume Anchors, which reserve a span of space. Nominal anchors reserve neither void nor space but designation, and the Division of Contextual Anchoring has ruled twice (in 3C-201 and again in 3C-207) that a nominal anchor may be established inside a designated volume without the volume-keeper's consent. The Department of Ephemera has never accepted this ruling and continues to require a countersignature on its own floors.

The Register of Nominal Extents

All nominal anchors in good standing are entered in the Register of Nominal Extents, maintained by the clerks of the Department of Nominal Integrity. Each entry records the anchored name, the date of entry, the floor of custody, and the drift interval — the distance in description the subject may stray before the anchor is adjudged failed. The standard drift interval is three removes: a subject may become a colour, then a remembered colour, then the rumour of a remembered colour, but not a rumour of a rumour.

Entries are not removed from the Register when anchors fail. They are struck through and initialled, and the strike-throughs are read as a record in their own right. The Register's seventh volume is almost entirely struck through, and clerks still consult it when a new anchor begins to behave as though it has been entered before.

Incidents

In the winter of 3C-238, a nominal anchor was entered on the eleventh gallery of a floor catalogued only as Warm Corridor, Unswept, holding a transient warmth that had resisted two material anchors and one procedural attempt. The name assigned was "the warmth of a room one has just left." The anchor held for nine days. On the tenth, the corridor was found to be cold, and every subsequent visitor reported the sensation of having just left a room, although no room was present and the corridor has one door. The entry was struck through by Clerk Ondrej Vask, who appended the note: "The warmth has gone into the description. Recover the description and we may recover the warmth." Neither has been recovered. The corridor remains in the inventory.

A more orderly failure is recorded on Floor 4,411, where a nominal anchor was established for a sound heard only at the hour of changing lamps. The anchor held without incident for forty years and was retired by mutual agreement when the lamps were converted. The retired name was entered in the Register of Echoic Phenomena and may still be consulted; visitors report that reading it produces no sound, which the Department considers a success.

Dispute: the Annex Gamma question

The standing scholarly disagreement concerns whether nominal anchors fall under the authority of the Panel of Designative Harmony, which received jurisdiction over nominal anchors by the Fifth Concordance, Annex Gamma, or whether that jurisdiction extends only to the naming and not to the anchoring. The Panel maintains that the two are inseparable: a name that holds a thing is a designation, and all designations are its concern. The Department of Nominal Integrity maintains the contrary, noting that Annex Gamma was drafted to settle a dispute about spelling and never mentions drift.

The disagreement has produced the Principle of Direct Adjacency, which holds that authority over a name passes to whichever body last wrote it down, and the counter-principle of retained custody, which the Department has never had printed but cites constantly. Directive 14,899-δ was intended to close the matter and instead supplied both parties with a paragraph each. A joint recension has been in preparation since 3C-261.

Practical notes

Nominal anchors are established by entering the name in the Register and reading it aloud once, in the presence of two clerks. Only one of the clerks need be awake. Anchors may not be established on a Coincidental stairwell, nor on any floor currently undergoing re-indexing, nor during the hour of changing lamps.

Visiting clerks are reminded that an anchored name is not to be spoken twice in the same corridor.
