Immersion Guides' Mandarin Phrasebook (English and Chinese Edition) My favourite phrase book in Beijing.
Insider's Guide to Beijing 2008 Excellent guide book to Beijing - great for students and expats. Very comprehensive!
Streetwise Guide Beijing: The Inside Scoop from Local and International Experts Another excellent guidebook. I used it extensively and took it everywhere.
China (Country Guide) This is one book I wish I had. It's not available in China, so if you think you might need it, you'd better get it before you go.
