Letters : 'Self-Help' was a book on helping others Great book, shame about the title

In the extract from the Duke of Edinburgh's letter, the word centre is spelt incorrectly. Perhaps Prince Philip declined a dictionary, thinking it "enfeebling ... help from without" and instead relied on "self- help" in the form of his word processor's internal American spell-checker.
