Master Ledger for Atrium 5, Vol. 412, Folio 88

The Master Ledger for Atrium 5, Vol. 412, Folio 88 is the authoritative register of Atrium 5 and, by extension, of every summons, transfer, and deferral passing through its north vestibule. Folio 88 is chiefly known as the deposition copy of Section 6 of the Eleventh Concordance, which sets out the procedure for opening and closing the Atrium's four service doors. It is bound in oxhide over oak boards, measures forty-one by twenty-nine centimetres, and is chained at the vestibule reading stand, where it has remained since the folio was rebound in the winter of 4,112. The chain is inspected quarterly. Visitors are permitted to turn pages without gloves; the ink will outlast them.

Structure and contents

Folio 88 divides into three parts. The recto carries the summoning rota for Atrium 5, a table of ninety-one names arranged by alcove rather than alphabetically, on the reasoning that alcove order is what a runner actually needs. The verso carries the deposition of Section 6, followed by the marginal apparatus: seventeen amendments, four of them struck through and re-entered, and one — the third — annotated in a hand believed to be that of the Warden of Perilous Folios, whose marginal note reads only "this door does not open outward, whatever the section says."

The lower third of the folio is given over to the Reconciliation Column, ruled in red, in which the atrium's daily returns are matched against the figures entered in the Master Ledger of Permitted Mechanisms. Where the two disagree, the Column records the disagreement and no more; resolving it is the business of the Quarterly Registry Reconciliation Schedule.

The Eleventh Concordance, Section 6

The clause most often consulted at the stand is the fourth, which governs who may hold an atrium door open during a summons:

"The door shall be held by the runner of the third grade, and by no other, save that where the runner is delayed beyond the ninth bell the holder may be any person whose name appears on the folio for that day, provided the door is not thereby held past the closing."

— Eleventh Concordance, Section 6, clause 4

The difficulty, long noted by the Master Cross-Reference Ledger's compilers, is that a person holding a door must necessarily appear on the folio for that day before the holding begins, and the folio is not written until the holding is complete. Clerks resolve this by entering names provisionally and striking the entry if the door fails. The struck entries are retained. There are, at present, 2,140 struck entries on the folio's supplementary sheets, and the practice of retaining them is defended in the Master Folio of Pending Evidence as a safeguard against recurrence.

The Great Re-Shelving dispute

Folio 88 acquired its present prominence through its treatment of the Great Re-shelving of Atrium 9. When Atrium 9 was re-shelved over eleven days in 4,109, its holdings were moved through Atrium 5 to reach the eastern galleries, and the question arose whether a summons issued in Atrium 5 could be served on a volume merely passing through it. The folio records the answer given by the duty clerk, one Halvern Straythe, who entered in the Column the single word "served," followed by the note "and the volume was not grateful."

Straythe's entry was challenged within the month. Impossible Topologies, Vol. XIV had already catalogued Atrium 9 as a space in which a volume may occupy two shelves at once, and it was argued that a volume passing through Atrium 5 under such conditions could not be said to be present there in the sense Section 6 requires. The Chronicles of the Mutable Atrium take the opposite view, recording that presence is a matter of the door and not of the shelf, and that Straythe was correct. The two accounts have not been reconciled; the Master Ledger of Settled Affairs contains no ruling on the point.

Amendment history

Folio 88 has been amended eleven times, most recently in 4,147, when the closing bell for the north vestibule was moved from the eighth to the ninth hour to accommodate the Ceremonial Ledger's processions. Each amendment must be entered first upon the Blank Folio, which serves as the master ledger for amendments to the Master Folio, and only then transcribed onto the folio itself. The transcription of the 4,147 amendment was made twice, in error, and the duplicate was not removed; readers are asked to consult the lower entry, which is the corrected one.

Access and custody

The folio is consulted at the stand and does not travel. Requests for removal are refused under the Master Folio's standing instruction that a master ledger leaving its atrium ceases to be a master ledger and becomes, in the Registrar's phrase, "a book with an opinion." Photographic reproduction is permitted for the recto only. The verso has never been reproduced, on the grounds that the deposition copy is itself the instrument and a copy of an instrument is not an instrument.

The folio was last collated against the Master Register of Volition in 4,153, and three names on the summoning rota were found to have no corresponding entry in that register. The discrepancy was noted in the Column and referred onward. It remains open.
