With the recent Netflix hit Tidying Up with Marie Kondo sparking a heated debate over her advice to keep only thirty books at a time, memes erupted defending the love of stacks. This frenzy shines a light on the compulsive urge to gather and hoard books, a condition known as bibliomania. Here are 10 things you probably didn’t know about this book‑obsession phenomenon.
10 Things You Can’t Miss About Bibliomania
10 The Infamous Book Bandit
Stephen Blumberg, famously dubbed the “Book Bandit,” hailed from Iowa and managed to amass a staggering 23,600 volumes. None of those tomes belonged to him; they were stolen from 327 libraries and museums spanning 45 U.S. states, two Canadian provinces, and the District of Columbia. A restless wanderer, Blumberg never sold a single book—he simply kept adding to his ever‑growing trove.
His knack for evading capture was legendary. He slipped through ventilation shafts, ducked down dumbwaiters, and once almost got crushed by a service elevator while attempting to scale its shaft. In a last‑minute scramble, he squeezed into a recessed inspection bay in the wall, narrowly escaping disaster.
The law finally caught up with him in 1990 when a friend, motivated by a $56,000 reward, tipped off the Justice Department. The FBI deployed a 12‑meter (40‑foot) tractor‑trailer to haul away his 19‑ton stash for cataloguing. Altogether, the collection was valued at $5.3 million.
During the trial, forensic psychiatrist Dr. William S. Logan testified that Blumberg suffered from bibliomania intertwined with schizophrenic delusions. After serving four and a half years behind bars, he was released—and promptly resumed expanding his epic library.
9 Not A Recognized Disorder
Bibliomania has been discussed for nearly two centuries, yet the American Psychiatric Association refuses to list it as a formal disorder in the Diagnostic and Statistical Manual of Mental Disorders. Even Oxford University Press defines the term merely as a “passionate enthusiasm.”
In the realm of psychology, bibliomania is understood as a symptom of obsessive‑compulsive disorder. Hoarding endless piles of books can wreak havoc on health and relationships when the relentless urge to acquire outweighs all other desires.
Medical professionals often prescribe the same medications used for other compulsive disorders, but drugs alone rarely suffice. Cognitive‑behavioral therapy remains the most effective treatment, helping bibliomaniacs set and achieve realistic goals.
8 A Fatal Case Of Book Madness
The Greek roots of the word—biblion (book) and mania (madness)—combine to form “bibliomania,” literally “book madness.” The earliest recorded use appears in a 1734 diary by collector Thomas Hearne, who wrote, “I should have been tempted to have laid out a pretty deal of money without thinking myself at all touched with Bibliomania.” At that time, it was deemed a mild form of insanity.
In 1750, Lord Chesterfield warned his son in a letter: “Beware of the Bibliomanie.” The caution underscored the growing awareness of the condition among the elite.
The first full‑blown literary examination arrived in 1809 when Thomas Dibdin published Bibliomania; or Book‑Madness. Written satirically, Dibdin portrayed the condition as a peculiar “neurosis,” dubbing it “the Book disease.”
7 Tsundoku
Bibliomania isn’t confined to the West. In Japan, the phenomenon is called tsundoku, describing the habit of amassing books that never get read. Unlike the negative Western view, tsundoku carries a more forgiving tone, acknowledging the good intentions behind the pile‑up.
Professor Andrew Gerstle of the University of London notes that the term first surfaced in 1879 as a joke about a teacher who owned a mountain of books but never opened them. Today, tsundoku also describes un‑tapped collections in other media—films, clothing, video games—essentially “vast, untouched software libraries.” It captures the gap between noble intent and actual consumption.
6 Book Curses
Ashurbanipal, ruler of the Neo‑Assyrian Empire, wore many hats: spymaster, king‑slayer, lion‑tamer, and—perhaps most intriguingly—bibliomaniac. Though kings rarely read or wrote, Ashurbanipal was a devoted scholar who founded the world’s first systematic library.
He coveted every clay tablet he could lay his hands on, treating books as prized war spoils. His obsession led him to amass hundreds of thousands of tablets, which he guarded fiercely. To deter thieves, he inscribed ominous curses on the tablets, warning would‑be robbers of divine retribution.
One such curse reads: “Whosoever shall carry off this tablet, or shall inscribe his name on it, side by side with mine own, may Ashur and Belit overthrow him in wrath and anger, and may they destroy his name and posterity in the land.” After two millennia of burial, the library resurfaced in 1849, revealing treasures like the ancient Epic of Gilgamesh.
5 Different Types Of Collectors
Bibliomania embraces a spectrum of collector personalities. Dr. Russell Belk, writing in the Journal of Social Behavior and Personality, identified the “taxonomic collector,” who strives to own every edition of a work, and the “aesthetic collector,” who gathers books that simply bring pleasure. Some collectors even develop a fetishistic relationship, treating their volumes as sacred objects.
Ruth Formanek, also cited in the journal, outlined five core motivations: extending the self through knowledge acquisition; seeking social connection by sharing material; preserving history to link with the past; financial gain; and pure addiction. Across the board, the driving force remains an intense passion for the items themselves.
4 A Safety Hazard
The allure of a towering stack of leather‑bound tomes can turn hazardous. As piles creep into kitchens, bedrooms, even bathrooms, they crowd living spaces, making daily chores a maze of precarious books. Trips and stumbles become routine, and the accumulated dust invites rats, cockroaches, ants, and termites.
Beyond the tripping danger, massive stacks block exits, turning homes into fire traps—books are highly flammable. In extreme cases, bibliomania can manifest as a compulsion to burn books, while some sufferers even develop “bibliophagy,” the urge to eat paper, adding another layer of risk.
3 The Baron Of Bibliomania
Sir Thomas Phillipps, a 19th‑century baronet, earned the moniker “Baron of Bibliomania.” He preferred the term “vello‑mania,” reflecting his obsession with both books and documents. Phillipps filled his tower with printers to reproduce his treasures, creating mountain‑sized archives that often never left their boxes.
His relentless collecting left bills unpaid and even caused structural damage—leaks went unrepaired as funds vanished into his ever‑growing hoard. A century after his death, his staggering collection—40,000 books and 60,000 manuscripts—was sold off piece by piece, heralded as the largest manuscript assemblage of the nineteenth century.
2 Caused By Trauma
Many bibliomaniacs trace their obsession back to early childhood, where book‑collecting becomes a coping mechanism for hardship. Psychiatrists suggest that the compulsion can serve as a defense against trauma or repeated abuse, allowing sufferers to mask pain behind towering stacks.
This protective behavior often spirals; the individual hides their trauma by surrounding themselves with books, refusing to confront the underlying issues. Left unchecked from youth into adulthood, the habit can evolve into a serious problem, affecting relationships and daily functioning.
1 The Extraordinary Librarian
In 1869, Dr. Alois Pichler earned the title “extraordinary librarian” at St. Petersburg’s Imperial Public Library. Yet his love for books went far beyond custodial duties.
Within months, a mysterious wave of theft swept the library. Guards suspected Pichler as the culprit; he was seen dropping books at the exit only to dash back and reshelve them, all while cloaked in a heavy overcoat he never removed. Over two years, 4,500 volumes vanished—ranging from perfume treatises to theological works.When finally accused, Pichler’s lawyer argued that his actions stemmed from an irresistible mental condition, labeling it a “mania” rather than a crime. The court, however, sentenced him to exile in Siberia, cementing his legacy as the archetype of bibliokleptomania—the compulsive urge to steal books for personal collection.
