You must seek permission(s) if you intend to reproduce any text or other intellectual property that is protected by copyright – unless your intended use qualifies as fair dealing.*
In the United Kingdom, the standard term of copyright in original text is 70 years beyond its author’s death, or 70 years from date of first publication if posthumous. Unless either copyright has expired or your intended usage qualifies as fair dealing, you must request formal permission from the publishers who control rights in whatever material you intend to exploit.
Penguin Random House UK is typically able to grant permission for use of material taken from books first published by one of the following, as detailed in the imprint page of their editions:-
Penguin Books Ltd.
The Random House Group Ltd.
Dorling Kindersley Ltd.
Rough Guides Ltd.
Please check that one of the above was the original publisher of a given title before contacting us for permission.
* Includes usage that is strictly personal, or for non-publication scholarly exploitation, or of short extracts (fewer than c.300 words) for criticism. See here for general guidance concerning fair dealing.
