Pocket Penguins is a series of books released by Penguin Classics in 2016. The series echoes the style of the original Penguin Books, with smaller A-format size, and tri-band design. The first 20 books were released in May 2016, and described by publishing director Simon Winder as "a mix of the famous and the unjustly overlooked". A Pocket Penguins series of 70 titles was published to celebrate Penguin's 70th birthday in 2005. It is known as the Pocket Penguins 70s and is available as a boxed set. A similar set of pocket Penguin 60s - this time only 60 books, each with 60 pages - was published to mark the company’s 60th birthday in 1995.
