Ladybird Expert (Series 117) was launched in January 2017 following the success of Ladybird for Grown-Ups. The books in this series are not parodies but instead use the classic format to serve as clear introductions to a wide variety of subjects, generally in the fields of science and history. The first book published and the inspiration for the series is "Climate Change" by the Prince of Wales, Tony Juniper and Emily Shuckburgh. Four more titles were released in 2017 by Jim Al-Khalili ("Quantum Mechanics"), Steve Jones ("Evolution"), James Holland ("The Battle of Britain") and Ben Saunders ("Shackleton"). The line was expanded with fifteen further books in 2018 and more titles were published in 2019.
