The top 10 neighbors for St. Martin's Press are almost entirely fellow book publishers — nine of the ten share its subcategory — and they cluster within a narrow similarity band running from 0.94 down to 0.91, the defining signature of a flat shape.
Hachette Book Group leads at 0.94, followed closely by Little, Brown and Co at 0.93 and Publishers Weekly at 0.93 — the one non-publisher in the top 10, a trade magazine whose audience composition nonetheless tracks the publisher cluster almost exactly. Simon & Schuster (0.93), Penguin Random House (0.92), Scribner (0.92), HarperCollins (0.92), Alfred A. Knopf (0.91), Riverhead Books (0.91), and Random House (0.91) round out the set. The spread across all ten is only three hundredths of a point — no single neighbor dominates, and none falls meaningfully behind.
What the flat shape and same-kind composition together reveal is an audience that is deeply embedded in the trade publishing world: the people who follow St. Martin's Press follow the major houses, imprints, and industry press as a coherent bloc, with no clear outlier pulling in a different direction.
