In the Sixties, there were no guidebooks to Asia, at least none that suited young shoestring travelers. No one on the hippie highway carried a copy of Fodor's 'Islamic Asia.' The route to spiritual enlightenment wasn't revealed in the pages of the latest Baedeker. Intrepids were on a journey of spontaneity and reinvention.

Berlin is all about volatility. Its identity is based not on stability but on change.

To me, Berlin is as much a conceit as a reality. Why? Because the city is forever in the process of becoming, never being, and so lives more powerfully in the imagination.

To me, it remains incomprehensible that a people who can design the Porsche 911 and sleek, white ice trains, who created the Bauhaus and speak at least three languages at birth, want to own twee Christmas figurines painted in gaudy colours, dress up in Bavarian lederhosen, and eat Haribo gummy bears.

The earliest maps were 'story' maps. Cartographers were artists who mingled knowledge with supposition, memory and fears. Their maps described both landscape and the events, which had taken place within it, enabling travellers to plot a route as well as to experience a story.

Good travel books, like travel itself, open the door to new worlds. In the strongest works the author's vision becomes our own, especially if his or her subject is a distant destination.

I grew up under the spell of London. Illustrator Kerry Lee's evocative 1950 wall map of the city hung above our breakfast table at home in Canada. Over my corn flakes, I traced the capital's high roads and medieval alleys.

The travel book is a convenient metaphor for life, with its optimistic beginning or departure, its determined striving, and its reflective conclusion. Journeys change travellers just as a good travel book can change readers.

London has always moved and surprised me, reinventing itself in ways both fresh and familiar. It's a contrary, complex and creative city, an anarchist of a thousand faces - fickle and unfailing, tender and bleak, ambitious and callous.

I don't see the value of boringly reporting the cold facts.

One of the most inexplicable characteristics of the Germans is their love of kitsch.

Mandy Sutter's 'Bush Meat' triumphs in its lean prose and true dialogue, in its disarming humour, in its evocation of a family divided by sexism and racism in 1960s Nigeria.

One of the most remarkable shindigs I ever attended was in Warsaw.
