Documentary Anchors

Documentary Anchors are a class of Conceptual Anchors employed to fix a documentary subject — a record, an attestation, a catalogue entry, or an entity whose existence is sustained chiefly by paperwork — against the tendency of such subjects to drift, lapse, or silently amend themselves. They are distinguished from Material Anchors in that the anchored object need not occupy any physical space, and from Nominal Anchors in that the anchor addresses the consistency of the description rather than the name alone. The Division of Contextual Anchoring maintains that Documentary Anchors are the oldest continuous anchor form in the Tower, a claim the Documentary Sourcing Division disputes on evidentiary grounds it has never fully set out.

Origins and the Kestrel Recension

The practice is conventionally dated to the Kestrel Recension of the Fourth Concordance, in which a register of anchorage types was appended to a schedule of weights and measures. The appendix, known as Schedule 11, listed six anchor forms, of which two are legible. The surviving text reads:

"An anchor shall be fixed to the paper and to the fact, and where the two are found to differ, the anchor shall be fixed to the paper."

— Kestrel Recension, Schedule 11, clause 3

Clause 3 is the founding text of the Doctrine of Documentary Realism, though the Doctrine's own recension places the sentence in a different schedule and attributes it to a clerk identified only by the seal of the Lower Registry. Both readings are cited in current practice, generally by whichever office finds the other's version inconvenient.

Operation

A Documentary Anchor is struck by fixing the subject's description at a determinate moment — usually the moment of first registration — and thereafter treating any subsequent variation in the description as a fault in the record rather than a change in the subject. The anchor's strength is measured in drift indices, expressed as the number of layers of description that may be added before the anchor must be reset. A drift index of 4 or above is regarded as serviceable. Most working anchors in the Registry of Registered Registries run between 2 and 3 and are reset annually in a ceremony that takes under four minutes.

Anchors are typically struck into a designated volume rather than a fixed point, since documentary subjects are rarely locatable in space. Where a subject does occupy a location — a vault, a clerk's desk, a disputed shelf — a fixed geospatial anchor may be substituted, though the Division discourages this on the grounds that it "confuses the paper with the place," a phrase that appears in its guidance notes four times without further explanation.

Documentary Anchors should not be confused with Absence Anchors, which stabilize a subject by regulating what is not said about it. The two are frequently used in combination, most visibly in the Calibrated Absence Anchors employed at sealed holdings; the compound form has a poor reputation following the Wexley Collation of 1198, in which an absence anchor was struck over a documentary anchor without a recording clause, and eleven shelves of holdings became consistently descriable but not, in any useful sense, there.

The Emendation Dispute

Scholarly disagreement centres on whether a Documentary Anchor resists genuine amendment or merely resists the appearance of it. The Doctrine of Documentary Realism holds that consistency in Documentary Humidity is the primary indicator of categorical stability, and that an anchor therefore binds the subject to its registered description absolutely. Against this, Librarian Ospra Venn argued in her marginalia that an anchor struck without an emendation clause is void upon its first correction, since a description that cannot be amended cannot be verified, and an unverifiable description is not a description but a decoration. Venn's position is not taught at the Scriptorium of the Third Landing, where her marginalia are catalogued under Unresolved Holdings and may be consulted by appointment.

The Seventh Concordance appears to settle the matter by requiring every documentary anchor to carry an emendation clause numbered in the margin. The Ninth Concordance, which is later and shorter, states that documentary anchors carry no clauses and that marginal numbering is a decorative convention. Both remain in force. In practice the Documentary Authentication directorate reads the Seventh and the Documentary Audit service reads the Ninth, and their findings are reconciled annually by a procedure no one has documented.

Failures and the Phantom Question

When a Documentary Anchor is allowed to lapse, the subject commonly survives as a description without a subject, or the reverse. Documentary Phantoms are the usual consequence; they arise most often during a Documentary Review or a cascade audit, when an anchor is reset while a reading is in progress. The Cascade of 1304 at the Sixth Spiral produced upwards of forty phantoms from a single anchor, all of them agreeing with one another and none of them agreeing with the shelf they were filed on. Documentary Sealing was developed in response and is now standard for anchors above drift index 5.

Anchors are inspected under Documentary Dissonance Practice, which records the point at which the anchored description and the anchored subject first disagree. Inspectors are required to log the disagreement and to take no action for one full working day. The rule is stated plainly in the inspection handbook and is observed, according to the Office of the Quartermaster of Stairs, without exception.

Inventory of Anchor Forms in Current Use

The Anchorage Roll of 1387 lists the documentary forms presently authorised, of which the following are drawn from the Roll without amendment:

• Single-clause documentary anchors, unstruck and hand-fixed.
• Marginal documentary anchors, carrying an emendation numeral.
• Composite documentary anchors, struck jointly with a conceptual or material form.
• Reserved documentary anchors, held unassigned against a future subject.
• Disputed documentary anchors, held in Division custody pending a ruling.

Reserved anchors constitute roughly a third of the Roll and have never been assigned. The Registrar of Reserves has twice petitioned to have them removed, on the grounds that an anchor held for a subject that does not yet exist is indistinguishable in the ledger from one held for a subject that no longer does.
