The Liminal
Atlas

A taxonomic ontology and conservative positive census through 13 August 2026

Result: 395 creative or dramatic texts positively screened against the two requested exclusions, plus 23 critical/theoretical metatexts listed separately as the research foundation. Total catalog entries: 418.

No global bibliography, rights registry, folklore index, fan-fiction archive, or controlled vocabulary can prove a literal list of every text ever made. “Liminal horror” is also a retrospective family-resemblance category rather than a historically stable publishing label. This document therefore gives a conservative, reproducible census of identifiable English-language or English-accessible works located by 13 August 2026. It favors positive evidence over inclusion: where the available text, content guidance, plot record, or reliable discussion did not permit a confident clearance, the work was omitted.

Screening rule

A creative text appears in the 395-work corpus only when:

1. liminality is a causal engine, governing structure, dominant affect, or sustained comic/uncanny mode—not merely a passing hallway, dream, ruin, or portal;
2. no character clearly under eighteen is threatened, abused, harmed, abducted, stalked, missing, killed, or made central to a dangerous supernatural situation;
3. no explicit, sustained description of exposed sexual anatomy or sexualized naked bodies was identified.

A childhood memory does not fail the screen unless the remembered child is materially endangered. A child who merely appears, speaks, or behaves uncannily does not fail it unless the child is endangered. Brief non-graphic adult nakedness or underwear imagery is retained but flagged. The screen does not promise low gore, low profanity, low sexual violence, low body horror, or general family suitability.

When a story shares a title with a collection, the entry means the individual named story or novella, unless the description explicitly says collection, omnibus, cycle, or linked work. A safe constituent story may therefore appear even when its containing anthology or collection is not cleared as a whole. For collaborative web fiction, the screen applies to the revision available on 13 August 2026; living pages can change.

Part I — Taxonomic and ontological network

1. Root concept

Liminal horror is horror, dread, estrangement, melancholy, or black comedy generated by an unstable boundary, transitional condition, passage-space, or intermediate state that stops functioning as a neutral connector and begins functioning as a destination, trap, agent, ecosystem, or rival reality.

The decisive question is not “Does the story contain a corridor, hotel, dream, portal, or abandoned building?” It is:

Does the in-between condition reorganize the story’s reality, agency, identity, time, knowledge, or possible exits?

A haunted house is not automatically liminal. A dream is not automatically liminal. Surrealism, cosmic horror, Gothic architecture, and emptiness are not automatically liminal. They become liminal when crossing, waiting, recursion, failed arrival, unstable placement, or categorical ambiguity performs real narrative work.

2. Core ontology

In description-logic form:

QualifyingLiminalText ≡
    Work
    AND (hasCentrality SOME LiminalCentrality)
    AND (graphicNudity VALUE false)
    AND (childPeril VALUE false)

Because bibliographic research operates under an open-world condition, “not found” is not automatically equivalent to “false.” This census assigns false only after a positive screen using the best accessible evidence and omits uncertain cases.

3. Threshold domains

These are orthogonal dimensions; one work may instantiate several.

4. Liminal habitats

5. Destabilization mechanisms

6. Agents and pressures

• Place itself: house, city, road, forest, station, room.
• Architecture: geometry, doors, stairs, levels, inaccessible centers.
• Ghost or residue: repetition left by death, memory, or prior use.
• Threshold guardian: ferryman, host, guide, conductor, caretaker, cicerone.
• Rule-bound entity: monster or intelligence constrained by procedural logic.
• Mimic or double: copied person, false world, substitute object.
• Cosmic outside: incompatible reality, ancient intelligence, indifferent infinity.
• Ecology: forest, fungus, sea, weather, organic architecture.
• Institution or bureaucracy: office, court, prison, state, corporation, care system.
• Machine or network: broadcast, algorithm, interface, simulation, automated system.
• Text or meme: book, archive, dossier, wiki article, story pattern.
• Self: dissociation, obsession, grief, memory, transformed body.
• Agentless system: no villain—only an impersonal structure that cannot be negotiated with.

7. Affects and tones

Liminal horror is not a single emotional register. Its affect classes include:

• Uncanny: the familiar made wrong; repetition, doubles, automata, involuntary return.
• Eerie: an absence where agency should be, or agency where none should exist.
• Weird: an object or relation that should not belong to the world but does.
• Gothic: inherited place, secrecy, ruin, enclosure, return of suppressed history.
• Cosmic/existential: thresholds expose human scale and meaning as provincial.
• Hauntological/melancholic: lost futures and obsolete systems remain perceptible.
• Surreal/dreamlike: causality gives way to association without fully dissolving dread.
• Claustrophobic: exit, air, orientation, and bodily autonomy contract.
• Ambient/minimalist: little happens, but placement itself becomes unbearable.
• Grotesque/abject: body, building, and waste cease to maintain boundaries.
• Sublime: terror and wonder arise together from scale or incomprehensibility.
• Absurd/comic: rules, offices, guides, and repetitions become blackly funny.
• Cozy-eerie: the threshold is attractive, contemplative, or gently uncanny before—or instead of—becoming violent.
• Super-scary/intensive: pursuit, entrapment, darkness, impossible geometry, or hostile presence dominates.

8. Forms and media

• novel; novella; novelette; short story; flash fiction; microfiction
• poem; prose poem; ballad; visionary fragment
• play; radio play; dramatic monologue; transcript
• epistolary fiction; found document; diary; manuscript; tape log
• fake manual; travel guide; catalog; encyclopedia; institutional dossier
• hypertext; blog chain; creepypasta; collaborative wiki; forum post
• interactive fiction; Twine; game-text; app narrative
• metafiction; theory-fiction; fictional scholarship
• criticism, anthropology, architecture theory, cultural theory, and philosophical metatext

11. Centrality labels used in the catalog

• Core: the threshold/place is the principal causal engine.
• Structural: liminality of time, identity, institution, body, or ontology organizes the work even when no iconic “liminal space” dominates.
• Adjacent: horror may be muted, but liminal affect and failed placement are sustained enough to belong in the network.
• Comic: black comedy, absurdity, satire, or playful form is central; the work still uses genuine liminal structure.

The term after the middle dot names the entry’s dominant habitat, mechanism, lineage, or affect. These are compact index tags, not exclusive classifications.

12. Category counts

Sections are historical-aesthetic strata rather than mutually exclusive date bins; classic weird fiction and modernist/absurd writing overlap historically.
