Annexed Stacks

Definition and Jurisdictional Basis

An Annexed Stacks is a shelf-body—contiguous runs of shelving, with their attending catalogues, ladders, and floor-loading—whose administrative identity has been formally transferred from its parent floor to a receiving jurisdiction without the physical removal of any material. The transfer is recorded in the Tower Coordinate Grid and, where the volume concerned exceeds three bays in depth, in the Registry of Annexed Floors. An Annexed Stacks is distinguishable from an Annexed Atrium in that the latter is a dependent architectural space derived from a parent, whereas the former is a self-sufficient body of holdings placed under a new authority: the architecture stays where it is; only the obligation to it moves.

The primary authority governing such transfers is the Third Concordance, whose Vell Doctrine holds that accession of a shelf-body does not enlarge the receiving floor's holdings but merely its responsibility for them. The distinction is preserved in every recension of the Third Concordance and is the cause of most of the litigation.

The Tarrow Reclassification and Its Revision

The practice was regularized in the winter of the year 890-Σ, when the Lower Stacks had accumulated four hundred and twelve uncatalogued bays at their eastern terminus and no mechanism existed to assign them a parent. Clerk-Marshal Onvel Tarrow proposed that the bays be severed from the Lower Stacks and annexed to an "artificial parent"—a receiving designation with no floor of its own, existing solely to hold the accession. The measure was carried under the Edict of Perpetual Review and, for eighteen months, four hundred and twelve bays belonged to a parent that could not be visited.

The arrangement failed on a privilege question: a borrower may not be escorted to a parent that has no stair. Tarrow's receiving designation was dissolved in the following year, and the bays were returned to the Lower Stacks under a negotiated instrument since known as the Tarrow Revision. Clause 3 of the Revision states the operative principle:

"That no shelf-body shall be annexed to an authority incapable of being walked to, nor shall any receiving floor decline an accession on grounds of absent stair, save where the instrument of annexation so provides."

— Tarrow Revision to the Register of Accessions, clause 3

The Revision is generally taken as a rebuke to the office of the Registry of Annexed Floors, which had approved Tarrow's measure and subsequently declined to comment on it.

The Coordinate Grid and the Anchoring Trigger

Every Annexed Stacks must be specified by at least two grid marks in the Tower Coordinate Grid, one at each terminus of the shelf-run, and a third at the point of administrative contact, which is customarily the first upright of the first bay. Where a phenomenon emerges within Annexed Airspace above the shelving, the emergence triggers Jurisdictional Anchoring under the Third Concordance, and the Anchored volume is fixed to the termini recorded at the time of the transfer rather than at the time of the emergence. The discrepancy between these two moments has produced at least nine reported incidents, of which the most cited is the loss of an entire cross-aisle at Floor 48-A to an anchorage fixed to a terminus that had been dismantled eleven years previously.

The current schedule for grid verification is annexed to the maintenance ledger of the Sigma Regulator, and verification of shelf-bodies is conducted in the third week of each quarter. Do not reshelve during verification.

Disputed Doctrine

A persistent disagreement divides the Limbus Stacks from the office of the Precedent of Recursive Jurisdiction over whether an Annexed Stacks may itself annex. The Limbus position, advanced most fully in the commentary attached to Concordance 7, Annex Δ, is that annexation is a property that travels with the body, and that a shelf-body which has once been under a receiving authority retains the power to receive in turn. The Recursive Jurisdiction office holds the contrary: that a receiving authority inherits responsibility but not competence, and that a stacks which annexes beyond the second degree is void ab initio.

The question has practical force because the second-degree shelf-bodies are in active use and their voidance would require the withdrawal of some two thousand catalogue entries. The dispute was heard under the Marrow appeal and remitted; it has stood open since. The Silent Stacks Excavation (890-Σ) is sometimes cited on one side or the other and is never decisive.

Recorded Inventory

The following bodies were listed as annexations in progress at the last full accounting of the Registry of Annexed Floors:

• Lower Stacks, eastern terminus — accession under the Tarrow Revision, unscheduled.
• Floor 1,337, The Autonomous Stacks — self-annexed; see the entry at the floor itself.
• Spiral Theta — annexed within the jurisdiction of the Bureau of Queue Management, accession suspended pending queue clearance.
• Floor 1117, eastern bays — accession incomplete; the duty log is preserved in the Registry of Annexed Floors.

Practical Notes

Access to an Annexed Stacks requires the visitor to state the receiving floor rather than the parent floor, as the parent may no longer be reachable. Ladders are not transferred with the body and must be requisitioned from the receiving floor, which is frequently in a different grade of the Tower and may hold no ladders. Where the accession is over three bays, a second ladder is required in all cases.

Clerk Tarrow, whose grievance is still filed under the Revision, is recorded as having requested leave to appeal his own measure and having been granted it. The appeal has not been heard. The office of the Registry maintains that it has been heard and dismissed, and cites a minute that cannot be produced.
