Quadrille is launching a new series of pocket guides aimed at "demystifying a wide and eclectic range of subjects".
The series is called The Knowledge, and will be published in hardback form, priced at £10. The books will text-led and feature line illustrations, aimed at both the gift and self-purchase market.
Six launch titles will be published in June, covering red wine, jazz, the periodic table, opera, whisky and stargazing, with more titles planned for 2016.
Series editor Jane O'Shea said: "The guides are designed to provide an accessible introduction to each subject but also to be of interest to the more-informed reader. As the first six titles demonstrate, the series will include subjects of known popular interest as well as some where there is a real gap in the market."
