Guardian Books' nearest audiences span book publishers, literary magazines, general-interest magazines, and news publishers in roughly equal measure — no single neighbor type dominates, and the scores compress into a narrow band from 0.97 down to 0.96 across the top 10.
The shape is flat. Alfred A. Knopf leads at 0.97, followed closely by London Review of Books (0.97), Granta (0.97), The Millions (0.97), and Salon (0.97) — a spread that includes a Book Publisher, two Magazines, a Blog, and another Magazine, all within a hundredth of a point of each other. Rounding out the top 10: Serious Eats (0.97), Publishers Weekly (0.96), Farrar, Straus & Giroux (0.96), NYRB Classics (0.96), and LA Review of Books (0.96). By subcategory, the top 10 breaks down as four Book Publishers (Knopf, FSG, NYRB Classics, and — just outside the strict top 10 — Publishers Weekly as a Magazine), four Magazines, one Blog, and one Website. No other News Publisher — Guardian Books' own subcategory — appears in the top 10. The cross-kind character is the defining feature: the audience that follows a books vertical of a news publisher looks, in shape, more like the audiences of literary imprints and review magazines than like other news publishers.
The flat distribution across these subcategories suggests an audience defined by a consistent literary-intellectual orientation rather than loyalty to any single format or platform type.
