Joint Attribution

Definition and Jurisdiction

Joint Attribution is the practice by which a single holding is assigned to two or more responsible sources at once, none of which is subordinated to the others. It is distinguished from Provisional Attribution in that the multiplicity is not a state of ignorance awaiting correction, but a settled finding: the record asserts that the property, quality, or authorship in question genuinely belongs to more than one source simultaneously.

The practice sits in permanent tension with the Principle of Singular Attribution, which holds that for any property or quality of a holding there must be one definitive source. Joint Attribution is therefore never the default. It is entered only on ruling, and only under the procedural shelter of the Protocol for Contradictory Attribution, whose three-Librarian review panel (established under Clause 31 of the Nineteenth Concordance) may certify a folio as Jointly Attributed rather than Self Contradictory. The distinction is fine and has consumed the better part of a century of grazing disputes between floors.

History: Floor 90 and the Great Schism

The doctrine arose as an expedient during the Great Schism, when the Office of Structural Paradox faced holdings that had acquired two irreconcilable creators and could not be reorganised without dismantling half the affected shelf. The Mending Protocol for Floor 90 — the instrument now generally cited as the Protocol for Contradictory Attribution itself — permitted certain resistant holdings to retain both attributions rather than elect one.

What began as a temporary shelter hardened into procedure almost immediately. By the recension of 11,912 the panel had certified 4,301 Jointly Attributed folios on Floor 90 alone. The Vault of Ambiguous Records now carries a standing annex for joint holdings, entered in two hands on facing pages, a physical arrangement the vault's keepers defend as "the only filing that does not lie."

"Where two hands are equally evidenced, the ledger shall show two hands, and no ruling of the panel shall be read as preferring one brightness to another."

The Realist–Purist Dispute

The principal scholarly controversy concerns the legal status of joint holdings. The Purist reading holds that Joint Attribution merely suspends the Principle of Singular Attribution pending eventual reconciliation, consistent with the codified principle that all contradictions in the record are temporary states. On this view there are, strictly, no joint holdings — only holdings awaiting partition. The Realist school maintains the opposite: that the finding is terminal, and that the partition of a joint holding constitutes a new attribution requiring fresh evidence, not a clarification of the old. In practice the Office of Systematic Attribution arbitrates Realist while drafting Purist, a habit its own auditors have twice noted without remedy.

The question is not idle. Arbiter Silt ruled in the winter of 11,948 that the two composers of a jointly attributed processional could not be counted separately for the purposes of the Attribution to a Single Composer restriction, thereby admitting the work to a festival from which it had been excluded for eleven years. The ruling was appealed, upheld, and then quietly contradicted by a floor circular issued the same season. Both remain in force.

Known Difficulties

Joint holdings produce disorders that single attribution does not. When a joint holding is cited, both attributions must be cited, in the order entered; clerks who abbreviate to the first-named are corrected under Clause 14 of the Concordance of Unfinished Works. Disputes about the order itself are filed on Form 7,117-δ and deferred to the Office of Systematic Attribution for a numbering ruling that may take up to nine years.

The School of the Unnamed Scribe has produced a substantial literature on the "shared hand" — folios in which the two attributed sources are, on internal evidence, indistinguishable. The School maintains that such cases should not be attributed jointly at all but transferred to the Dream Registry, where sources are recorded as concurrent rather than plural. The panel has declined to adopt this position four times, most recently without discussion. The School's Precedent of the Unnamed Scholar remains its strongest authority and is not accepted by the panel as binding above Aperture 400.

Record-Keeping

Joint holdings are entered in the Attribute Ledger under a doubled seal, and no clerk may close a joint entry alone. The following are the classes presently recognised at the Vault:

• Concurrent attribution — both sources evidenced independently and neither derived from the other.
• Sequential joint attribution — two sources, one demonstrably completing the other, with the division unrecoverable.
• Distributed attribution — a single quality evidenced in parts held on separate floors.
• Anomalous joint attribution — where one of the attributed sources is itself a holding.

The fourth class is rare and much disputed; nine instances are recorded, of which two are the same instance filed twice under different names, a duplication the vault has declined to resolve on the ground that resolving it would alter the count.

Relation to the Wider Catalogue

Joint Attribution should not be confused with the treatment of contested cantatas, which proceed separately under Attribution Arbitration for Contested Cantatas, nor with the metacollection, which resolves plurality by absorption rather than joint entry. Its closest neighbour in practice is Provisional Attribution, from which it is separated by a single finding of the panel and a considerable quantity of paperwork. Concordance 17, Clause 4, governs the transfer between the two, and Nineteenth Concordance Amendment 7 exempts joint holdings from the general prohibition on doubled seals. The exemption was granted in 11,921 and has never been reviewed.
