  • "I am absolutely thrilled to have a copy of the Collins English Dictionary. If I am ever cast off on a desert island, this is the book I want to have with me. What a wonderful gift."

    Judi Dench

    John Grant, Crossword Editor, The Times

    Professor B A Harris, University of Dublin

    Peter Wrobel, New Scientist
