It was Lonely Planet's 'Sydney (Condensed)' (2nd ed. June 2002). The maps and information were spot on. The suggested itineraries for walks were great and very helpful. It was also how I found my accommodation. While you can still get the 'Condensed' guide, the most recent edition (Nov. 2004) is now called 'Best of Sydney' - I recommend this guide for anyone who is planning a short trip to Sydney.
