Physicist Brian Cox, "Grand Designs" presenter Kevin McCloud and TV choirmaster Gareth Malone are among the authors whose work has been adapted for a new e-book series for HarperCollins.
The titles in the Collins Shorts series, drawn from chapters of existing titles, will cost 99p each and are being presented as an easy way into non-fiction.
Launching today (19th November), the first six titles are available on all digital devices, but according to Collins, work best on devices that support full colour and animation.
All the books are between 20 and 40 pages long, with the launch titles including How the Universe Will End by Professor Brian Cox, How to Make Your House a Home by Kevin McCloud and How to Enjoy Classical Music by Gareth Malone.
More titles will be made available in December, including Why do Birds of Paradise Dance? by David Attenborough and Errol Fuller.
