Permanent Fade

Permanent Fade is the terminal classification applied to a catalogued holding whose Perceptual Fade has advanced beyond the recoverable range and has been certified as irreversible under the terms of Certification to Permanent Holdings. Where Perceptual Fade names a process and the Fade Index measures its degree, Permanent Fade names an outcome: a holding still present in the stacks, still numbered, still listed, but no longer available to the senses of any reader who has not already seen it. The designation is administrative before it is physical. A holding is permanently faded when the Librarians say it is, and the saying is recorded in triplicate.

Permanent Fade is not to be confused with Permanent Glow, its opposite and, by longstanding convention, its procedural twin: the one a holding that cannot be stopped from showing, the other a holding that cannot be made to show at all. Both fall under the Permanent Directives, and both are distinguished from ordinary storage in Temporal vs. Permanent Stasis.

Origin: the Permanent Fade incident

The term entered the Concordances by way of catastrophe. In the late Spiral 17 era, a batch of Lysander Parch failed to reset after its 72-hour cycle. Inscriptions that should have faded at the close of the third day remained legible and, worse, remained fixed — and the failure propagated to the holdings shelved in contact with the batch. The episode, known thereafter as the Permanent Fade incident, was the first formally documented instance of Perceptual Fade, and it produced the permanent data loss for which the Fade Assessment Amp Restoration was later devised as the standing remedy. That the incident shares its name with the present classification is a source of continuous confusion in the indices; the Addendum to the Seventeenth Concordance addresses the matter in a footnote of eleven lines and resolves nothing.

LLAS-001, the first holding to undergo a completed Fade Assessment Amp Restoration, holds a confirmed Fade Index of 4.0 — the scale's ceiling — yet is not classified as permanently faded, having been restored. Clerks are reminded that the Index and the classification are separate instruments.

The Certification procedure

Certification requires a Fade Assessment conducted under the Manual of Perceptual Hygiene, followed by the Rite of Silent Assessment, in which the assessing Librarian attests that the holding was sought and not found, twice, on separate days, and that the seeking was properly witnessed. The Reverse Index is consulted throughout. If the assessment returns a Fade Index of 4.0 and the Rite is uncontested, the holding passes to Permanent Fade and its entry is amended in the Permanent Designation Code.

The Rite has a maintenance requirement that is frequently overlooked: assessors must be provided with a second lamp, unlit, for the duration of the silence. No Concordance explains this. Clerks who ask are referred to the Principle of Permanent Placement.

Dispute: the Astral Annex conflict

Two recensions govern the classification and they do not agree. The Ninth Concordance, Annex 2, holds that a holding certified as permanently faded may never be reclassified, on the ground that "what the Rite has closed, the Index shall not reopen" (Ninth Concordance, Annex 2, clause 6). The Fourteenth Concordance, Annex 1, permits reclassification on the petition of any Librarian of the third grade or above, provided the petition is sealed and the seal is not the petitioner's own. Both have been cited in the same proceedings. In the matter of the Astral Annex, a reading room certified at Fade Index 4.0 in the winter of Spiral 22, a third-grade Librarian named Ottoline Vesh petitioned for reclassification under the Fourteenth and was refused under the Ninth; the room remains certified, and Vesh's petition, sealed by a colleague, remains in the file, unread and uncited.

"Where two Concordances speak to one holding and neither yields, the holding shall be maintained in the condition in which it was last seen."

Known holdings

The register of permanently faded holdings is short and the entries are terse. A representative selection, as of the current recension:

• Astral Annex — reading room; certified Spiral 22; still assigned a number and a name.
• Hollow Stair, Floor 0 — stairwell; the floor number predates the certification and has not been revised.
• The Blank Folio — a bound volume; its shelf position is recorded, though the shelf is not.
• Unnamed holdings — forty-one entries, each listed by number only, the names having been lost with the sightings.

In practice

Permanent Fade is administered from the Office of Faded Holdings, whose clerks maintain the register and answer inquiries. An inquiry about a permanently faded holding receives, by rule, a reply stating that the holding exists and is unavailable. Inquirers who write a second time receive the same reply, which the Office regards as confirmation that the holding remains in its certified condition. Whether a permanently faded holding is still there is not a question the Office entertains. It is listed; it is numbered; it is certified. Access to the register itself is by appointment, and appointments are made in the morning only.

Of the holdings certified to date, fewer than a dozen have ever been seen again by anyone. The Librarians record these sightings, seal them, and take no position on them.
