Addendum 2004

Addendum 2004 is a single-sheet instrument of the Fourth Concordance, ratified on the eleventh of the month of Grinders in the year ordinarily counted 2004 by the Tower's own reckoning — the coincidence of number and year is noted in the archive as one of the Concordance's more tiresome ornaments, and clerks of the Scriptorium of Seals are instructed not to remark upon it in the presence of visiting parties. The Addendum is brief, comprising a preamble, four clauses, and a schedule of two lines. It concerns the classification and disposal of documents that have been catalogued but cannot be located.

Its full title, as engrossed, is Addendum 2004 to the Fourth Concordance, Being an Instrument for the Naming of Holdings Not Presently Held. It is not to be confused with Addendum 12, which shares a numeral in the reduced form used by the lower reading rooms, nor with the much older Addendum Proviso, although the two are commonly cited together and are, in the opinion of the present compiler, cited together too often.

Background: the Missing Shelf

Between the winter of the year 1997 and the spring of 2002, three successive surveys of the eastern stacks reported a discrepancy of shelf-space on Floor 44 that could not be accounted for by ordinary loss. The floor's inventory listed four hundred and six holdings; the shelves accommodated three hundred and eighty-nine. Seventeen holdings were recorded, sealed, and cross-referenced, yet had no physical extent.

A preliminary memorandum of the Office of Acoustic Cartography, dated to the second survey, observed that the floor "returns a sound of a room that is full, whatever the shelves hold," and recommended that the discrepancy be treated as acoustic rather than archival. The recommendation was received and filed, and the file itself was subsequently found to be one of the seventeen. The Office has never been entirely forgiven for this.

Matters came to a head when a reader of the Seventh Addendum to the First Concordance requested Holding 44:112, a treatise on spiral geometry, and was issued instead a blank card bearing the words presently held elsewhere in a hand no one in the reading room recognised. The Directorate of Stacks treated the incident as a procedural irregularity; the Bureau of Recensions treated it as a category error; both parties, characteristically, were correct, and Addendum 2004 was their compromise.

Clauses I to IV

Clause I establishes the class of coincidental holding: any catalogued item whose shelf-position, call-number, and seal are in good order but whose material form cannot be produced on demand by a Librarian of the third grade or above. Clause II provides that a coincidental holding shall be entered in the register of the floor to which it belongs, in a hand distinct from the hand of the register.

Clause III is the operative provision and the source of most of the subsequent difficulty. It requires that the holding be named aloud once, in the presence of two witnesses, at the hour the floor closes. The naming is recorded; the recording is sealed; the seal is entered in the register under Clause II. The Addendum is silent on what the holding is called before it is named, a silence that the Office of Procedural Degradation has described as "generative."

Clause IV forbids the practice of naming a coincidental holding twice. The prohibition is absolute and has been tested only once, on Floor 44 in the winter following ratification, with consequences recorded in Addendum on Procedural Degradation and not repeated here.

"A holding named twice is a holding with two addresses, and a thing with two addresses will go to the quieter one."

Scholarly Dispute: The Counting Question

The principal controversy surrounding Addendum 2004 is whether a coincidental holding counts toward the census of its floor. The Second Concordance holds, at Annex 9, that all catalogued items count, whether present or not, on the reasoning that a census counts what the Tower has and not what the Tower can find. The Fourth Concordance, by the hand of its own Addendum, implies the opposite.

The Bureau of Recensions has ruled twice on the question and reached different conclusions in the same year. Its first ruling, in the month of Keys, held that the Addendum's silence on prior naming was "an omission of the Fourth Concordance, not an instruction"; its second, in the month of Weights, held the reverse. Both rulings remain in force. The Census Field Manual: Provisional Addendum advises enumerators to record the figure and its absence separately, and to leave the total blank.

A minority school, associated with the Office of Acoustic Cartography, maintains that a coincidental holding should not be counted at all, since on the Office's own measurements it occupies no volume and returns no echo distinct from the room. This school is respected and small. Its leading advocate has not been seen on Floor 44 since 2003.

Relationship to Addendum Kappa

Addendum Kappa governs recursive anticipations, and its evidentiary conditions for declaring a Recursive Descent are invoked whenever a coincidental holding is found to anticipate its own entry in the register. That the two instruments now overlap is an accident of drafting: Addendum Kappa was intended for documents that anticipate future amendments, and not for documents that anticipate their own naming.

The overlap was formalised, without anyone's clear intention, by Ordinance Kappa-19, which formalises Clause III of Addendum Kappa; the Ordinance cites Addendum 2004 in its preamble as "the instrument of the absent object," a phrase the Directorate has asked to have struck and the Bureau has declined to strike. The current position is that a coincidental holding which anticipates its own naming is a recursive anticipation of the second order and must be reported to both offices, which then correspond about it until the floor closes. The correspondence is itself filed. It has, on fourteen occasions, been a coincidental holding.

Maintenance Note

The eastern stacks of Floor 44 remain open to readers of the second grade. Lanterns are not permitted below the fourth gallery, and the register must be returned to the desk by the hour of closing, named or unnamed. The seventeen original holdings are still listed. None has been produced on demand since 2002, and the desk has stopped asking.
