Floor 117

Floor 117, officially registered as the Resonant Scriptorium, is a mid-tier archival and inscription floor situated between Floor 71 and Floor 881. It functions as a primary repository for what the Fifth Concordance terms "Aural Ephemera"—recorded sounds that are not, or are no longer, being produced.

Architectural and Acoustic Profile

The floor’s defining structural characteristic is its near-perfect acoustic resonance, achieved through a labyrinthine network of vaulted, lead-lined limestone galleries. The galleries are arranged in a double-helical configuration, a design formalized by the 31st Reshelving Decree of Year 842 of the Archive. This architecture ensures that any sound produced within the floor persists for a minimum of 117 seconds before decaying below the threshold of audibility, a figure which gives the floor its numeric designation. The galleries are lined with millions of wax-cylinder recording spools, each housed in a brass-mounted niche inscribed with a frequency- and timestamp-based indexing code. The ambient temperature is maintained at a constant 13°C to preserve the integrity of the wax medium.

Core Holdings and Procedural Function

According to Annex Δ of the Third Concordance, Floor 117 is charged with the cataloguing of three specific categories of sound:

• Terminal Echoes: The final sounds emitted by objects or phenomena that have ceased to exist within the Tower, such as the closing hum of the now-dismantled Hermetic Carillon on Floor 451, or the last drip from a dried-up cistern on Floor 1024.
• Unvoiced Phonemes: Sounds that were prepared for articulation but were never uttered, typically harvested from the chambers of rhetoricians, diplomats, and petitioners immediately before significant, subsequently cancelled, addresses.
• Ambient Absences: Recordings of silence from spaces known for specific ambient noise, such as the now-quiet reading room of the 311th Floor, archived as a reference for comparative acoustic studies.

Procedure dictates that all deposits must be accompanied by a Form 117-Δ, "Certificate of Cessation," validated by a Librarian of Notational Authority.

Operational Controversies

The floor’s mandate is a persistent source of inter-departmental dispute. The clerks of Floor 714 (the Provisionary Allotment) have repeatedly filed petitions arguing that the collection of "Unvoiced Phonemes" constitutes a pre-emptive archival action, violating the principle of "Manifest Existence Before Cataloguing" outlined in the Second Concordance. Conversely, scholars from Floor 900 contend that the "Ambient Absences" are not true holdings, but merely meta-data about other holdings, and should be reclassified under their purview. These disputes are routinely deferred to the adjudicators on Floor 707 (the Harmonic Reshelving), where they remain perpetually under review.

The 117-Second Rule and Its Implications

The enforced 117-second resonance period has unintended procedural consequences. All clerical work on the floor—conversations, footfalls, the scraping of chairs—is itself recorded and archived, creating an infinite regress of meta-recordings. A dedicated sub-gallery, Gallery 117-Ω, is reserved for these "procedural echoes." A controversial edict from the Librarians (Clause 117.7.41) states that any sound which repeats identically across 117 separate procedural echoes is to be extracted and promoted to the status of a true holding, a process that has, to date, yielded only seventeen sounds, all of them variants of a standard-issue wax cylinder stylus being set into its cradle.

Access and Concluding Notes

Access to the raw holdings of Floor 117 is restricted to Librarians with Audiographic Certification. However, derivative finding aids, primarily in the form of spectrographic analyses printed on resonance-dampened paper, are available for cross-reference on Floor 412 and Floor 712 (the Ornamental Grotto). The floor's position between the low-frequency archival systems of Floor 71 and the structural lattice-work of Floor 881 is considered acoustically strategic, though some cartographers of the Canted Halls argue this placement is merely a notational convenience. As with all floors dealing with ephemeral subjects, the ultimate ontological status of its holdings—whether they are sounds, or merely the records of sounds—remains, by Concordance, undebated and undefined.
