Sotheby's New York Book Week runs June 11–25, 2026, per the house's published calendar — a two-week series of books-and-manuscripts sales headlined by Fine Books and Manuscripts, Including Americana, whose live sessions take place June 24 and 25 within an online bidding window opening June 11. The material, per the house's preview coverage, spans medieval illuminated manuscripts through modern literature in single-owner and various-owner sales — the paper market's full range under one roof at the season's midpoint.
The scale marker: the week's evening sale carries a low estimate north of $25 million, with a George Washington letter to Benjamin Franklin estimated around $1.5 million leading the Americana material in the related series, per HENI's report on the lineup. Those numbers place Book Week among the year's significant auction events in any category — a reminder, documented across the market's recent reporting, that rare paper has been trading at levels once reserved for canvas.
What the week means for readers who write: the catalogs are the show. Book Week's previews put manuscript pages — authorial drafts, letters, annotated books — on public display and in free online catalogues, which function as the best-illustrated survey of literary process published each year. The same pages that scholars reconstruct composition from pass through these rooms, and the week's results (which categories strengthened, whose letters multiplied estimates) become the market data the libraries and dealers read for the rest of the season.
The calendar context: Sotheby's runs the Book Week format twice yearly — the late-June edition now arriving, and the December edition closing the year — with Christie's books department holding its own summer calendar in parallel. The sales follow a spring that already saw the art market's flagship report document a return to growth, and the June evenings will be the first major test of whether paper rides the same wave. Daily Pencil publishes information, not collecting advice; dates, lots, and viewing hours are at the house's site.
