Harry Potter Among the Antiquarian Booksellers

Dear bibliophiles, good day.

By Olympe Marcelet, inspector of platforms, emphatic keywords and the priced miracles of the bibliophilic digital market.

Platforms hate publishing their figures. They love publishing their records. AbeBooks — the world’s largest marketplace for used and antiquarian books, owned by Amazon since 2008 — thus publishes, every quarter and every year, its list of “Most Expensive Sales”. A modest editorial genre: ten entries, ten prices, one sentence of wonder per lot. Nobody reads these lists twice.

I have read them all, or nearly: the annual reviews from 2021 to 2025 and the latest quarter published, some sixty documented sales, with prices, dates and particulars of the copies. It is little, it is declarative, it cannot be verified, but every line comes from the platform itself. And a platform that boasts is a platform that confides.

The lead character of these league tables wears round glasses and has a scar on his forehead. Harry Potter and the Philosopher’s Stone is second sale of 2023 ($85,620 for a copy of the true first edition of 1997, printed in five hundred copies), number one of 2024 ($105,700 for a lot of four first editions, of which we are told the true first can be recognised by a misprint on page 53), and number one of the second quarter of 2026 ($29,900). The absolute record, all years combined, goes to a Thomas Pynchon collection of 246 pieces, sold for $125,000 in 2023.

Around them the cast is stable: Tolkien almost every year (The Lord of the Rings in a full-leather-bound lot at $40,300 in 2025, two Hobbits in the second quarter of 2026 alone), Oscar Wilde, Melville, Byron, Frankenstein, and an army of childhood books — The Velveteen Rabbit in dust jacket ($28,000), a complete Narnia ($40,000), the entire Swallows and Amazons series ($45,900), Dune, a signed Dark Tower, a print of the last Calvin and Hobbes strip ($35,000). Of the fifty sales in the 2021–2025 reviews, thirty-five concern works in English; in 2023, ten out of ten, and nothing earlier than 1778. I know neither these buyers nor their reasons — the platform publishes none. I merely note that, in these league tables, the books one reads at ten or twelve have settled into places one would have thought reserved for incunabula.

Let us now look not at the titles but at the entries, for that is where the market confesses its criteria. None of these prices pays for a text: the text of Dorian Gray has been readable free for a century. The entries stress something else — the complete number line, the original dust jacket, the “unfaded colours”, the copy number (63 of 250, signed), the signed binding, the box. In 2025, two copies of the same Constitutions of the Free-Masons of 1723 sold in the same year, one for $32,650, the other for $31,000.

Provenance, for its part, has changed in nature. The Harry Potter of 2023 comes from the Edinburgh public library, which had lent it twenty-seven times before disposing of it; the entry mentions a restoration. A lending-copy past, restored into the bargain, and the entry nonetheless details it as a title to glory.

Two details, finally, that I add to the file without superfluous comment. In 2021, a facsimile of Audubon’s Birds of America — a facsimile, of 1972 — sold for $36,635, more than the 1516 edition of Euclid’s Elements listed the same year. And two years running, the gospel of stockbrokers dominated science: Benjamin Graham’s Security Analysis ($29,000 in 2021), then Jesse Livermore’s How to Trade in Stocks, a speculation manual of 1940, signed ($40,000 in 2022) — $15,000 more, that year, than Bernoulli’s Hydrodynamica. The ranking grades books not on their contributions but on their promises.

And the French books? They exist, but count them: a small ten out of sixty sales. And their profile is instructive. They are not literary first editions — no Proust, no Baudelaire, no Romantic — but almost always fine illustrated books: Pierre Louÿs’s Les Chansons de Bilitis illustrated by George Barbier and bound by Schmied ($34,300 in 2025), the complete run of Derrière le miroir with its original lithographs ($35,000 in 2021), Dalí portfolios. France, seen from these podiums, is a workshop: it counts there for its engravers, illustrators and binders more than for its texts.

Two exceptions, which are not. The autograph letter of Leibniz of 1710, at the head of the 2025 review at $44,000, is written in French — but it is the French of learned Europe, that of a German writing to a Scot. And the only Jules Verne in the league tables, Around the World in Eighty Days, sold for $30,000 in the American first edition, autograph note enclosed: the only French novelist of these rankings sells there in translation. As for French first editions, I shall refrain from concluding that they are worth nothing — they simply do not pass through there. They have their sale rooms, their booksellers and their circuits, which do not send their figures to Seattle. The absence, here, measures no lack of love; it measures a platform frontier.

One last detail, discovered while checking the subsidiaries. ZVAB, the old German-language portal for antiquarian books, bought by AbeBooks, also publishes its “teuerste Verkäufe”. Since 2022 these are the same lists — same books, same order, prices converted at the day’s rate, the Pynchon becoming €115,000. In 2021, though, ZVAB still published its own sales: a calligraphy of 1719, a Hermann Hesse watercolour, a Kreütterbuch of 1539, a letter from Schumann — a continental, learned world, with round prices in euros, vanished not from the market but from the press release. The subsidiary now translates the triumphs of the parent company.

The finding, in sixty sales, fits in one sentence: the summit of the largest antiquarian book market is no longer old, no longer Latin, no longer learned. It is English-speaking, it is the age of our childhoods, and it sells in a dust jacket.

That is not forbidden. It was enough to count.

IGLI Clinical Files: The Gilt-Edge Syndrome

Dear bibliophiles, good day.

Special Zoobibliological Surveillance Service. IGLI. By Dr. Fulbert de Cuirac, sworn veterinarian of printed entities, expert to the Bureau of Abnormal Manifestations of the Book, appointed for disorders of owner attachment and heraldic-bibliological rejection phenomena.

File opened at the request of: Mr. B., amateur, 16th arrondissement, worried owner.

Entity concerned: octavo volume of the mid-19th century, full red chagrin (grained leather), ornamented spine with raised bands, gilt on all three edges, very fine general condition. For clinical discretion, we shall call it the Gilt Patient.

According to the provenance register, the entity spent forty years in the window of a Latin Quarter bookshop, exposed in broad daylight, before Mr. B. acquired it at a public sale. Since its installation at the latter’s (corner shelf, middle position, respectable neighbors), the entity has shown behavioral disturbances that the owner describes, with the touching imprecision of non-specialists, as “the fidgets.”

The facts were recorded over three weeks by the owner, then verified by the service. Every morning the entity is found shifted by a few millimeters toward the lit end of the shelf, on the window side. Pushed back into place, it reoffends. During the home inspection, Miss Lépine, my assistant, found on the floor fine deposits of gold powder tracing a path of about fourteen centimeters, what the service, in its nomenclature, calls a vanity trail (traînée de vanité). The neighboring volumes, two honest half-sheepskins with no gilding, show an abnormal lateral compression, like subway passengers at rush hour. They are making room. Modest entities always make room.

Placed under observation at the service, on our calibrated shelving, the entity confirmed the picture: systematic orientation of the gilt edges toward the light source, whatever the initial position; reflections described by the staff as “provocative” in hours of strong sunshine; and a marked refusal of darkness. Placed in closed storage as a test, the entity developed overnight an onset of tarnishing that our control specimens of gilding, stored in the same conditions, did not show. It tarnishes on purpose. We are dealing with blackmail.

The service diagnoses gilt-edge syndrome, a classic form of vainglorious heliotropism (Splendor compulsivus, variety vitrinae nostalgicus): acquired inverted photophobia following prolonged exposure in a shop window during the formative years. The entity spent forty years being looked at; it contracted the shopfront disease, which consists in mistaking light for love. The domestic shelf, with its egalitarian dimness where an Elzevir is worth a morocco, is for it a social demotion that its organism rejects. Differential diagnosis: we ruled out simple mechanical slippage (the shelf is level, Miss Lépine set her own spirit level on it, and hers forgives nothing) as well as the intervention of a cat, a hypothesis always advanced by owners and almost always slanderous.

The service’s recommendations, in order. Do not yield to shop-window blackmail. Permanent display would aggravate the syndrome and, incidentally, fade the chagrin: vanity punished where it sins, which is morally satisfying but bibliographically regrettable.

Second, rotation of esteem: fifteen days per quarter on the living-room display stand, announced to the entity in advance. Gilt entities put up with everything except improvisation.

Third, neighborhood therapy: place on its left a 17th-century Elzevir in ivory vellum, modest and perfectly printed. Prolonged contact with discreet glories is the only known long-term treatment for vanity, in books. In owners, the service promises nothing.

Fourth, follow-up: new inspection in six months. Miss Lépine will keep the register of displacements, which she has in fact already opened, numbered and paginated unasked, as is her habit.

Prognosis favorable. The entity is not malicious; it was simply loved in public too young.
