A wide range of guidebooks is available for every Asian country, catering to everyone from backpackers to luxury travellers. There are some general guides to all Asian countries, but the fewer countries that are covered means the more detail there will be. If you're visiting several countries, regional guidebooks can be useful. Single country guides tend to offer more comprehensive information. Compare several guidebooks to see which one fits your interests. Some provide detailed historical and cultural information, while some spotlight where to find the most exciting nightlife or the best shopping. Pay attention to the maps, as some are easier to decipher than others. If you're traveling by train, bus or car, invest in a detailed road map.
