There still is no substitute for a good LP guide when I am going to visit a new place - not Trip Advisor or other websites, and no other guidebook I have come across. It is important to mention that LP is oriented toward a certain kind of traveller - a backpacker, or tourist who is looking to have authentic experiences of foreign lands while paying modest prices - someone like myself. There is however enough solid info in their books for people on group tours or who want to have a certain level of comfort. I am a fan, and have been for a while.
Having said that, I am not sure I would purchase this book again. India is big and complex, and the 1200 page book required to provide a good overview of it was not handy for my daypack. I do see that there are books for north and south India, and there is something called Discover India also - those might be more practical. But as an overview of the whole country, and one with useful sections and maps for a wide range of locales, it is hard to imagine the job being done better. I read the 150 page India Today section at the back of the book, the introductory segments at the front, and the pieces on the areas I visited, and all were clear, useful, and thoughtfully put together. Still, none of it prepared me for the swarming streets, the vivid colors, the traditional cultures, the gastric distress (which I was expecting), and the previously unknown diversity that India had in store for me - but I am not sure any book could have done that.
