Travel Guide Books (i.e. Frommer's, Lonely Planet, etc. ...)? - lonely planet scotland

Who knows if there are guides to the British Isles? Looking for a book with England, Scotland, Ireland and Wales, but so far I have not found a book with 4 countries. If anyone knows a book or a book mark with this kind of travel guide, please let me know! Thank you.
