Say what you will about globalization, but it does offer major perks for Anglo-bibliophiles in the form of Amazon.co.uk, the British version of the online book retailer. You can pick up the U.K. edition of, say, ”Harry Potter and the Order of the Phoenix” ($13.75). Or become the first on your block to read Martin Amis’ ”Yellow Dog” ($19) and P.D. James’ ”The Murder Room” ($14.50), which don’t hit U.S. stores until November. Other early titles now available: Pat Barker’s ”Double Vision” ($19) and ”The Full Cupboard of Life” ($11), the fifth in Alexander McCall Smith’s ”No. 1 Ladies Detective Agency” series — both due Stateside in 2004. (You can also preorder the new book by Bridget Jones creator Helen Fielding for delivery in early December.) The site charges roughly $6.50 per shipment and an additional $5 per book. Not exactly cheap as chips but a good solution for Yanks seeking a quick Brit-lit fix.
