PURCHASE THE BOOK THROUGH YOUR favourite seller, several mail-order firms, or through Columbia University Press with a discount.*** E-books are instant. Belatedly, after particular coronavirus disruptions, copies are now stocked in Australia/NZ, or should be soon, and at a much better recommended price, $57.95AUD.
***Here is the Columbia link to use the friendly promo code CUP30 for a 30% discount. Before delivery, the Columbia site quotes $35.00 US and £30.00. With discount and postage to Australia, and improving exchange rate, I recently made the total $52.44 AUD.
