Mac Barnett, author of more than 70 children’s titles and the national ambassador for young people’s literature, released his first adult‑focused work, *Make Believe: On Telling Stories to Children*, in May. The manifesto‑style book urges adults to prioritize picture books and imagination over reading metrics. Within 48 hours, Barnett’s tour hit New York, Washington and the Library of Congress.

Barnett’s most incendiary claim appears on page 22, where he adapts Sturgeon’s Law to assert that 94.7 percent of kids’ books are crud. Fellow picture‑book writers slammed the line on Instagram, TikTok and Substack, arguing it trivializes a market already strained by bans and shrinking library budgets. The outcry underscores how tightly linked author reputation is to publishing economics.

Library officials reminded ambassadors to avoid politicizing their platform, noting Barnett is paid as an independent contractor and must focus on “vital aspects” of children’s literature. The controversy may pressure the Library of Congress to tighten guidance for future ambassadors, while publishers watch for any dip in sales of picture‑book titles linked to the debate. Barnett’s influence now hangs in the balance.
