  1. No. 1 on this list. Finnegans Wake

    James Joyce · 1939

    Very Difficult44 hours

    Finnegans Wake appears on 108 university syllabi (Open Syllabus, 50th percentile) and holds a Wikipedia article in 39 languages. It is listed on the Modern Library 100 Best Novels and published by NYRB Classics. Syllabus presence is lower than Ulysses because the book is taught almost exclusively in graduate Joyce seminars and advanced modernism courses — its difficulty makes undergraduate adoption rare.

  2. No. 2 on this list. The Waste Land

    T. S. Eliot · 1922

    Very Difficult1.4 hours

    Taught in schools: Pacific Senior Secondary Certificate – English

    Included in: Great Books of the Western World

    Eliot shattered the conventions of English-language poetry by splicing together fragments of six languages, Grail legend, and London pub talk into a single 434-line collage that made modernism unavoidable. No poem before it had turned cultural disintegration itself into a formal principle.

  3. No. 3 on this list. Ulysses

    James Joyce · 1922

    Very Difficult47 hours

    Included in: Bokklubben World Library

    Ulysses appears on 1,017 university syllabi (75th percentile, Open Syllabus Project) and features on the Modern Library's #1 Best Novels list, Le Monde's 100 Books of the Century, TIME's All-TIME 100 Novels, and the BBC Big Read. Wikipedia covers it in 36 languages. Published in Everyman's Library and Penguin Classics, it has maintained continuous academic circulation since its 1934 US publication.

  4. In the Heart of the Heart of the Country was first published in 1968 and immediately positioned Gass — alongside Barth, Pynchon, and Coover — as a founding figure of American postmodern fiction. The NYRB Classics reprint with an introduction by Joanna Scott confirms its place in the American literary canon. It is taught in graduate programs in literary fiction and cited in essays on American experimental prose. Its canonical position is more secure in academic contexts than in general readership, placing it below Invisible Man or Blood Meridian but above most of its experimental contemporaries.

  5. No. 5 on this list. The Cantos

    Ezra Pound · 1970

    Very Difficult24 hours

    The Cantos appear on virtually every graduate-level modernist poetry syllabus and are the unavoidable centerpiece of Pound studies worldwide. The Pisan Cantos alone are canonical across multiple national literary traditions. While shorter Pound poems are more widely assigned at the undergraduate level, the full poem is central to any serious study of 20th-century Anglo-American poetry.

  6. The New York Trilogy stands as the defining work of American postmodern noir and one of the most influential experimental novels of the 1980s. It appears consistently on syllabi for postmodern fiction, metafiction, and American literature courses, and is cited as a foundational text in discussions of the detective genre's literary transformation. Published in the US by Penguin Books (1987 combined edition), it has remained continuously in print for four decades. It appears on numerous "greatest novels" lists and is central to critical discourse on identity, authorship, and the limitations of language in contemporary fiction.

  7. No. 7 on this list. How It Is

    Samuel Beckett · 1961

    Very Difficult6 hours

    How It Is appears on advanced modernism and postmodernism syllabi but rarely in broad undergraduate curricula — it is a specialist's Beckett text rather than the entry point (Waiting for Godot or Endgame fill that role). Wikipedia records the work in 6 languages with a 7,787-character article, indicating solid scholarly documentation but not wide popular reach. Among Beckett scholars it is considered essential; among general readers it is largely unknown.

  8. The Public Burning is Robert Coover's most ambitious and controversial novel — refused by seventeen publishers before Viking accepted it, then immediately pulled from paperback after a Nixon lawsuit threat. It appears in every major survey of American postmodern fiction (Hassan, Waugh, McHale), is taught widely in graduate seminars on metafiction, and is cited alongside Gravity's Rainbow and Giles Goat-Boy as the defining novels of the postmodern satirical-historical mode. Its canonical status exceeds its readership by a large margin.

  9. Mason & Dixon appears on graduate-level American literature and postmodern fiction syllabi, most notably in courses on Pynchon or on the 18th-century novel's legacy, but has not achieved the broad undergraduate curriculum placement of Gravity's Rainbow or The Crying of Lot 49. It appears on the Modern Library 100 Best Novels list and most 'great American novels' inventories. Wikipedia articles exist in over a dozen languages. Its length and difficulty limit classroom adoption compared to shorter Pynchon works.

  10. No. 10 on this list. Petersburg

    Andrei Bely · 1913

    Very Difficult31 hours

    Vladimir Nabokov named Petersburg one of the four greatest novels of the twentieth century, alongside Ulysses, Kafka's The Metamorphosis, and In Search of Lost Time. It is foundational to university syllabi in Slavic studies and comparative modernism globally, and appears on major world literature lists. Its canonical standing is high within literary circles and academia, though it reaches fewer general curricula than English-language modernist counterparts.

11–20 · 189 hours
  1. No. 11 on this list. Gravity's Rainbow · Thomas Pynchon · 1973

    Thomas Pynchon constructs an encyclopedic paranoid masterwork spanning 760 pages of rocket science, Pavlovian conditioning, corporate conspiracy, and encyclopedic digression. Tyrone Slothrop, American lieutenant in wartime London, discovers his sexual conquests map perfectly onto V-2 rocket strike locations—but the erections precede the impacts. Was he conditioned as an infant by sinister behaviorist Laszlo Jamf? Does a corporate-military cartel control history itself? Pynchon provides evidence for every paranoid connection while confirming none. The novel sprawls across 1944-45 Europe, from London under rocket attack to occupied Germany's anarchic Zone, accumulating hundreds of characters, corporate entities, chemical formulas, and historical conspiracies. Pynchon's prose shifts registers violently: technical manuals on rocket engineering dissolve into vaudeville routines, then into lyrical meditations on death and entropy. The vocabulary demands encyclopedic knowledge—thermodynamics, organic chemistry, Tarot, Rilke, film history, brand names. Readers navigate specialized jargon without glossaries, track characters who appear once and vanish, decode references to real and imaginary corporations. The difficulty is purposeful: Pynchon creates textual experience of paranoid information overload. His central symbol, the V-2 rocket, carries impossible symbolic weight: phallic death-bringer, technological sublime, gravity's rainbow parabola from launch to silent impact. The rocket arrives before its sound—death you cannot hear coming. Pynchon explores how technology transforms human consciousness, how corporations and states use Pavlovian conditioning for control, how empire produces extinction (the dodo, the Herero genocide). Concrete plot events—Slothrop's investigation, Roger and Jessica's doomed love, Blicero's ritual rocket launch—carry enormous abstract weight about history, causation, and freedom. The novel asks whether patterns are real or paranoid projection: does Slothrop's conditioning prove control, or is it coincidence interpreted as conspiracy? Pynchon withholds answers. The structure mirrors paranoid thinking—everything potentially connects, secret cartels manipulate history, individual agency vanishes into systems. Slothrop himself fragments as the novel progresses, appearing less frequently, dissolving into scattered references, finally disappearing entirely. The dissolution is structural: as Slothrop loses coherence, so does the narrative. Subplots proliferate, the center fails to hold, entropy increases. The ending places readers in a movie theater in Los Angeles, present tense, as the 00000 rocket descends toward them. The novel freeze-frames before impact, leaving readers perpetually awaiting the explosion. No resolution occurs—narrative, thematic, or moral. Gravity's Rainbow withholds the satisfactions of conventional fiction while demanding enormous interpretive labor. Its encyclopedic scope, technical difficulty, and paranoid plotting make it among English literature's most challenging novels. Pynchon proved unreadability and importance could coexist, that difficulty itself could be the point. The novel's influence on postmodern fiction is incalculable—it established new possibilities for combining history, science, and popular culture in maximalist form. Reading it requires surrender to accumulation, pattern-seeking without resolution, immersion in encyclopedic detail that may or may not signify. The reward is experiencing consciousness under late capitalism: paranoid, fragmented, overwhelmed by information, seeking patterns in noise, awaiting the rocket's silent arrival.

    Included in: Heinemann African Writers Series

    Widely taught across African literature curricula and regarded as the foundational novel of postcolonial Anglophone African fiction. Soyinka's Nobel Prize (1986) retroactively elevated its status; it appears on virtually every serious African literature syllabus worldwide.

  4. No. 14 on this list. Ill Seen Ill Said · Samuel Beckett · 1981

    An old woman lives alone in a stone cabin at the edge of a formless landscape. She watches Venus rise and the moon whiten the stones. She makes her slow way to a tomb bearing flowers. Twelve figures linger always in the distance — still, or receding — and she never sees one come toward her. A narrating eye watches her, reports what it sees, then immediately doubts its own report. 'Ill seen' is both title and method: Beckett spent his late career stripping the novel to whatever cannot be further removed, and Ill Seen Ill Said is among the most extreme results. There is no plot and almost no character in the usual sense — only perception failing to fix its object, language circling what it cannot say. The woman seems to be dying, or has always been dying, or is a figment the narrator cannot quite relinquish. A buttonhook trembles on its nail throughout; the stones encroach on the pastures year by year; and at the last a voice says: 'Know happiness.' At eighty-odd pages this is Beckett at his most concentrated — difficult, beautiful, and utterly unlike anything else.

  5. No. 15 on this list. Marks of Identity · Juan Goytisolo · 1966

    Marks of Identity is the opening volume of Goytisolo's Mendiola Trilogy, widely recognized as the most important work of experimental Spanish fiction produced under Francoism. It holds a secure position in world literature syllabi as a landmark text of anti-Francoist dissent written in a formal language learned from Faulkner, Sartre, and the nouveau roman.

    Harmonium appears on thousands of university poetry syllabi and is a fixture of American modernism courses. It is regularly listed among the foundational texts of American poetry, alongside Whitman's Leaves of Grass and Eliot's Prufrock — despite the database showing no captured syllabus appearances, Stevens's place in the academic canon is among the most secure of any twentieth-century American poet.

Perec's reputation — anchored also by Life A User's Manual — ensures its place in any serious survey of twentieth-century European fiction.

    Labyrinths is the standard English-language anthology through which Borges enters world literature curricula, taught in virtually every major comparative literature, Latin American literature, and 20th-century fiction course at universities worldwide. Published by New Directions in 1962, it established the benchmark for how Borges is read in translation and has remained continuously in print for over six decades as an essential classroom and critical text.

  9. No. 19 on this list. The Life and Opinions of Tristram Shandy, Gentleman · Laurence Sterne · 1759

    Included in: Bokklubben World Library, Great Books of the Western World

    Tristram Shandy is one of the most taught 18th-century English novels in university literature programs worldwide, appearing on virtually every course covering the development of the novel form, postmodernism avant la lettre, and experimental fiction. It consistently appears on lists of the greatest novels in the English language — Modern Library, Penguin Classics, academic consensus lists — and is the foundational text for any discussion of metafiction and narrative self-consciousness. Its canonical status is second only to Fielding's Tom Jones among 18th-century English prose fiction.

  10. No. 20 on this list. Vertigo · W.G. Sebald · 1990

    A narrator wanders through northern Italy in the late 1980s, haunted by a sense that the same catastrophe keeps arriving in different costume. He sits in a Verona archive reading newspapers from 1913—the year before everything collapsed—and finds himself unable to leave. In the second section, a figure called Dr K. travels from Vienna to Venice to Riva, conducting a doomed romance with a girl from Genoa and hearing, at a sanatorium dinner table, a general's theory that battles are decided by specific gravity, not willpower. These two time periods—the narrator's present and Franz Kafka's 1913—are laid over each other until they become one.\n\nSebald writes long, unhurried paragraphs that gather subordinate clauses the way rivers gather tributaries: you are always moving forward but the channel keeps widening. Photographs appear without captions. Characters arrive and dissolve. The dead hunter Gracchus, lost between worlds because a helmsman was distracted, recurs as the book's organizing myth—a figure for anyone unable to depart this life entirely.\n\nVertigo is Sebald's first book, the one in which his method first becomes fully itself: a narrator walking through landscapes saturated with historical catastrophe, finding that the past is not behind us but slightly displaced sideways, still happening, still unresolved. The final image is Samuel Pepys's fire seen from a dream of mountain passes—the city burning, pigeons dead on the pavement, the question 'Is this the end of time?' floating unanswered.

    A gargantuan, mind-altering comedy about the Pursuit of Happiness in America Set in an addicts' halfway house and a tennis academy, and featuring the most endearingly screwed-up family to come along in recent fiction, Infinite Jest explores essential questions about what entertainment is and why it has come to so dominate our lives; about how our desire for entertainment affects our need to connect with other people; and about what the pleasures we choose say about who we are. Equal parts philosophical quest and screwball comedy, Infinite Jest bends every rule of fiction without sacrificing for a moment its own entertainment value. It is an exuberant, uniquely American exploration of the passions that make us human - and one of those rare books that renew the idea of what a novel can do.

    Requiem and Poem Without a Hero are canonical texts of 20th-century Russian literature and essential documents of Stalinist-era witness poetry — required reading in Russian literature courses worldwide. No database records appear for this English translation's syllabus presence, but the works are universally taught in courses on Soviet literature, women's writing, and poetry of witness. The Wikipedia absence in this database likely reflects a data gap rather than actual obscurity: Akhmatova's works are foundational to Russian studies curricula.

About this list

These 100 books are the hardest-scoring eligible books currently in the catalogue. About 1,502 hours of reading in all. Difficulty runs from 74 to 80 out of 100 for the middle half of the list; the summit is Finnegans Wake at 94.

This is a computed ranking ordered by difficulty score, hardest first, with a consistent order for equal scores. Membership follows authors and co-authors, not translators or editors. The list keeps to literature: fiction, poetry, drama and philosophy, its novels, poems and plays first and its philosophy after them, and no more than three works by one author. Catalogue coverage and the historical canon both limit what this list can represent.

When we matched the Canons dataset to our catalogue in October 2026, our canonical-status scores rose with the number of school curricula, publisher series and lists in it that cite a work: the median score was 72 for books one such source cites, 84 at two, 88 at three, 92 at four and 93 at five or more. Prizes are left out of that count. Outside the state curricula, the dataset’s sources choose mostly from what has been translated into English or French, so it is a weaker check on other literatures.

Questions people actually ask

What are the hardest books to read?
Ranked hardest first by difficulty score: Finnegans Wake by James Joyce, The Waste Land by T. S. Eliot, Ulysses by James Joyce, In the Heart of the Heart of the Country by William Gass and The Cantos by Ezra Pound. ReadingRate ranks 100 such books, each with a difficulty score and a reading-time estimate.
Can I read any of these books for free?
15 of the 100 open in ReadingRate's reader with a free account, from public-domain editions: The Waste Land, Ulysses, Troilus and Criseyde, A Portrait of the Artist as a Young Man, Dream of the Red Chamber and 10 more.
How long would it take to read the top ten?
About 264 hours, at an average pace of 250 words a minute adjusted for each book's difficulty: 132 days at two hours a day. Set your own pace on the page and the list's reading times change to it.
How hard are the hardest books?
Most of this list sits between 74 and 80 on ReadingRate's 100-point difficulty scale, where 40 to 55 is moderate. The summit is Finnegans Wake at 94. Every entry carries its own score, so a reader can pick a great book at a difficulty they will finish.
Is Ulysses harder than Finnegans Wake?
No. Ulysses scores 89 and Finnegans Wake 94: Ulysses is hard chapter by chapter, Finnegans Wake on every line. Both rank in the top six. A Portrait of the Artist as a Young Man, at 78, is the gentler way into Joyce.
Why is so much of this list philosophy and theory?
Because the score measures two things at once: how hard the sentences are and how hard the meaning is. Dense argument in a specialist vocabulary scores high on both, which is why Lacan, Derrida, Adorno and Deleuze sit beside Joyce and Pynchon.
How is difficulty measured, and what does it miss?
Nine dimensions, from vocabulary and sentence structure to symbolic density and how much an ending withholds, each scored out of 100 and combined. It measures the text, not the reader, and it leans on meaning: The New York Trilogy scores 87 for how much it withholds, though its sentences are plainer than anything else in the top twenty. Each book's page shows which kind of hard it is.
