by Kaye Webb in 1967 with the promise to Allen Lane that "It will make children into book readers". Though by 1987, it had become uneconomical and evolved into the schools-only Puffin Book Club, at its height the club had 200,000 subscribers and held regular Puffin Exhibitions, and its magazine Puffin Post appeared quarterly for many years, resuming publication in January 2009. Colony Holidays (predecessor to ATE Superweeks) ran Children's Literature Summer Camps for members of the Puffin Book Club. Fifty or so children from all over Britain who loved reading would spend a ten-day holiday together, and popular children's authors such as Joan Aiken, Ian Serraillier and Clive King would spend a few days with them.

The 1990s continued to see new writers join Puffin and in the 21st century the brand still shows heroes and heroines familiar with children such as Artemis Fowl, Percy Jackson, Max Gordon, Mildred Hubble and Scarlett, while stars such as Kylie Minogue and Madonna have written for Puffin. 2020s In 2023, Puffin pursued goals of cultural reform through edits to at least 10 of the classic works of Roald Dahl, making hundreds of changes to Dahl's works to remove words like "fat", "ugly", and "crazy", and references to gender. Phrases such as "boys and girls" became "people" or "children". Puffin explained that these changes were part
