Penguin Pocket Philosophy Hardbacks
Although rather smaller than the rest of Penguin’s clothbound classics collection (about 10 cm x 17 cm), and made of a finer weave linen cloth binding, the mostly philosophical non-fiction titles included in the original Pocket Pocket Hardback Classics collection (selected because they have “changed the history of thought”) may be considered a very closely related series.
The first 10 titles in this series were released in 2014 , with two more following in 2015, featuring two toned covers, including matt foil decorations by the ever-talented Coralie Bickford-Smith stamped onto the binding. The text block is glued (not sewn) but the pages are acid-free and they include coloured endpapers, head & tail bands, and a bound-in ribbon bookmark. The cover designs featured geometric patterns, intended to be symbolic of the nature of the texts as timeless pieces of literature.
However, for later printings of these first books, as well as the later titles in the series that were released in 2020, the linen bindings were replaced with similar paper cover designs that use only a single block of colour. Therefore, make sure to track down a first printing of the initial 12 titles if you are after the highest quality edition.
