For those like me who can't live without maps, there are plenty of them. Each chapter starts with an area map that has numbered location markers, and other pages have highway and train maps, a six page "Street Finder", and more.
As well as information on all the sights to see in this great city, you get "The History of Boston", "Boston Through the Year", "Travelers' Needs", with hotels, restaurants, entertainment, etc. A "Survival Guide" that covers emergency, banking, and practical concerns, and is a must for any foreign visitors to the city, ends this most useful of all guide books.

I lived in the Boston area for many years, and appreciated its rich history and beauty, and there is no single guide that represents the city as well as this one.
With sturdy construction and terrific photography, reproduced on thick, glossy pages, if you're travelling to Boston, or any major city (I also have the Chicago, San Francisco, and New York City books), Eyewitness Travel Guides are the first, and maybe the only, guide book you'll need.
