The Endnotes

The apparatus you can hold in your hand

Most of Infinite Jest's architecture is inferred — the ring you only see once you have finished, the Sierpinski self-similarity you have to be told about, the withheld chronology you have to assemble. The endnotes are the one piece of the design you can literally hold between two fingers: 388 of them, running from page 983 to page 1079, a second book bound into the back of the first, requiring a second bookmark and a physical flip every time a superscript number sends you there. This essay is about that apparatus as its own subject — what actually lives in the back of the book, why Wallace put it there, and what the flipping does to a reader. The claim that the notes are one span of a larger structure — ring, gasket, withheld year, Hamlet scaffold — is worked out in structure-and-hamlet, whose endnotes section stacks the scholarly functions; what follows cross-links to that argument rather than repeating it, and dwells instead on the texture of the thing. (In this archive each of the 388 endnotes has its own page, glossed and linked to the scenes it touches.)

What lives in the back of the book

The endnotes are not a scholar's afterthoughts appended to a finished story; whole scenes live there and nowhere else. The clearest case is a tennis match that never appears in the main text at all. The pre-match challenge between Pemulis and Freer — with a weeping thirteen-year-old Postal Weight on the locker-room bench, and Pemulis delivering a comic-metaphysical sermon that math is the one thing you can trust ("you can trust math") while he gears up — is staged entirely inside endnote 324 (scene n324). It runs more than four thousand words, and it ends on a genuine cliffhanger: Stice bursts in with "Troeltsch's got Wayne on the air and Wayne's lost his mind" (scene n324), and the scene simply stops. The payoff — Wayne's on-air breakdown, Pemulis working out that his own pilfered Tenuate was behind it, and deLint sweating him in the Dean's office afterward — does not return to the main narrative either. It is relayed to another endnote (scene n332), so that a load-bearing plot event (John Wayne, the school's most reserved star, cracking open over the campus PA) plays out as an endnote-to-endnote handoff, exiled from the body of the novel twice over. Wallace was not exaggerating when he told Lipsky there was plot you would miss.

The same is true of the machinery the ending debate turns on. The reader gets DMZ's basic pharmacology in the main text — the drug "is synthesized from a derivative of fitviavi, an obscure mold that grows only on other molds" (scene 050, p. 170) — but the plot that makes it matter plays out in the back of the book. The conversation in which Pemulis quietly pitches it to Hal — a one-time transcendent interlude before Tucson; undetectable, since "DMZ doesn't show up on a G.C./M.S."; originally intended, he relays, to induce transcendent experiences in chronic alcoholics at the Verdun Protestant Hospital in Montreal — happens in an endnote (scene n321), the same note where Hal edges toward deciding to quit everything and Pemulis warns him that if you need it and walk away, "You die inside." The most argued-over drug in the ending debate does its decisive plot work in the notes.

And the endnote most often called the book's skeleton key is the filmography: endnote 24 (scene n024), a four-and-a-half-thousand-word catalogue of James Incandenza's complete film output, styled as a straight-faced archival document — "The following listing is as complete as we are able to make it" — with release states (UNRELEASED, lost, litigation-blocked) for each title. It is the one place a reader can reconstruct the genealogy of the fatal cartridge, and it plants the question the whole plot hangs on in a single clause of apparatus: certain of Incandenza's high-conceptual projects' agendas required that they be "titled and subjected to critique but never filmed, making their status as film subject to controversy." The question of whether the Entertainment exists as a finished object is first opened not in a scene but in a footnote's fine print. The notes also carry the book's running comedy of pseudo-scholarship — fake pharmacology, mock-taxonomic asides, the pedantic [sic]s and usage rulings that language-grammar takes up — so that the apparatus reads, by turns, as thriller, as reference desk, and as a joke about reference desks.

The author's own account

Wallace's own explanation of the notes is unusually direct, and it comes in two registers. The design intent is in the April 1994 pitch he made to his editor, Michael Pietsch (reported in dtmax-2009-the-unfinished): the endnotes would "allow[ing] a discursive, authorial intrusive style w/o Finneganizing the story" — a way to keep the digressive, over-explaining voice without collapsing the whole book into Finnegans Wake — and they would "mimic the information-flood and data-triage" of future American life, making the reader "go literally physically 'back and forth' in a way that perhaps cutely mimics some of the story's thematic concerns." He offered to "fight w/all 20 claws to preserve" them against Pietsch's counter-proposal of footnotes, and staked the whole gambit on its being "the best way to get the exfoliating curve-line plot I wanted." The pitch's own vocabulary — flood, triage, back and forth — is already the reader-experience argument in miniature.

The reception register is in the 1996 book-tour conversation with David Lipsky (lipsky-becoming-yourself), where Wallace describes the reader's freedom rather than the writer's method: "it's a very different book depending on whether you read the endnotes or not. Or whether you read them when the numbers direct you to them or afterwards, or before." He is blunt about the cost of skipping: "There's just a whole lot of plot stuff that isn't clear, if you don't read the endnotes." Asked whether he meant the book to be hard or easy, he answers, "The book was designed to be both, I guess." That the apparatus survived at all is itself a design decision he made under pressure: a second round of cuts proposed in 1995 fell heavily on the apparatus — "A lot of 'em being footnotes," in his account — and he accepted only about half of them, keeping the rest by choice; the cut history the-editing-of-ij reconstructs in full. One honest qualifier travels with all of this: the endnote system was a comparatively late invention, pitched in April 1994 largely as a way to manage a manuscript that had grown unmanageable. The notes are load-bearing in the published book, but the book was not conceived around them from the first page.

The apparatus was defended inside the family too. Wallace's sister Amy — whom he paid to proofread the manuscript as he mailed it to her in enormous envelopes — recalls taking him to task over the notes, telling him nobody wants to read that tiny type, and losing the argument; she suspects her objection only made him the more determined to keep them (paraphrased from audio; amy-wallace-havens-unedited-interview-2009). A family member's memory rather than a compositional record — but it agrees with the documented history: every recorded attempt to talk Wallace out of the apparatus, his editor's and his sister's alike, failed.

Four things the apparatus does

The secondary literature stacks four compatible readings onto the notes, each of which structure-and-hamlet synthesizes at length; in brief, the endnotes work as quarantine — confining the residual metafiction to the back of the book so the story can be told without a narrator's consciousness taking the throne (mcmorrow-ma-thesis); as interface — the flipping modeled on a tennis rally, engagement that makes a demand, against television's engagement that makes none (entertainment-addiction-tartu); as cruft training — some notes are deliberately, provably pointless, and learning to triage them is practice for the information surplus the Entertainment's victims cannot survive (identifying-stasis-venice, via Letzler); and as a disruption/addiction double — the notes both break the spell of immersion and hook the reader into the text's own loops (boswell-understanding-dfw). A reader-response account sharpens the same point: the notes force actions a reader would not ordinarily perform, pushing her out of absorption and "into a paratextual mode" of reflection — the endnotes' interruption read as the moment the reader is made to think for herself (henry-language-of-landscape-mccarthy, via Cioffi). The Hamlet-as-constraint reading touches the apparatus only by extension — Walsh takes the difficulty of the text at large as the constraint-writing method showing rather than failing, without treating the endnotes themselves — and that reading rests on a single scholarly witness, graded open (walsh-american-hamlet-thesis-2014, via structure-and-hamlet).

Fractured attention as the point

Under all four functions runs one argument, and it is the essay's central claim: the endnotes make the reader enact the book's subject. A novel about an attention economy — about entertainment engineered to capture and hold the eye until nothing else can — is built so that its own form refuses to hold you still. You are made to break your own concentration, to triage what matters from what is filler, to do physical, effortful work for a payoff that is sometimes a real plot revelation and sometimes a joke at your expense. The difficulty is not something the design costs; it is what the design does. Weighed against the novel's own pages, the archive grades the endnotes' standing as essential architecture of the published book strongly-supported — and not on the author's statements alone. Three distinct mechanisms inside the apparatus carry it independently: the endnote-to-endnote relay with its cliffhanger (scene n324, scene n332), the nested lettered and inline sub-notes that turn a single endnote into its own layered document, and the transcription machinery that routes Hal's own dialogues through the back of the book — with the April 1994 pitch as heavy corroboration (the structure adjudication). The one caveat that stays on record is the composition fact above: the apparatus was a length-management invention of April 1994, which caps any reading that the book was architected around its notes from conception.

The counter-record

The case is honest only if it admits how much of the reception has hated, skipped, or quietly deleted the notes. The most concrete evidence that the endnotes are felt as essential is the fight over the audiobook. When the 2012 recording first shipped without them — the decision made, its narrator recalls, from higher up, with the filmography alone running about an hour aloud and no way for a listener to bounce between files — the reaction was months of fan fury and one-star reviews, and eventually the endnotes were recorded after all as a separate, still-uninterleavable file, a reversal the podcast record credits to a reviewer's insistence that a version without them could not be recommended (gc-ep018-sean-pratt-ij-audiobook, paraphrased from audio). The medium could not carry the apparatus, and stripping it produced, audibly, a different and lesser book — which is Wallace's own claim, confirmed by the market.

Against that stand the readers who find the notes a needless imposition, the "cruft" complaint that the deliberately pointless notes are just deliberately pointless, and the perennial advice to skip them. The reception also keeps re-reading the device through its own moment: one reader in the novel's thirtieth-anniversary discussion calls the three-quarter-page footnotes "an inside joke at the time" that now reads as a figure for how compulsively we consume and stack information (general online discussion), and a reader in a different forum hypothesizes that the footnotes carry "a completely different plot," pointing to the way even a fact as basic as the state of Joelle's face can differ depending on whether you read them ([hn-threads-2026-07-10]). That last point is the whole matter in one observation: the notes are not optional apparatus but a second channel of the story, and the book you read is decided by whether you follow them.
