Each map appears three times; the page opposite each map page contains a location map and alternating listings called "essentials" (banks, hospitals, landmarks, libraries, pharmacies, police, post offices, schools, supermarkets), "sundries/entertainment"(coffee, copy shops, farmer's markets, gyms, hardware stores, liquor stores, movie theaters, nightlife, pet shops, restaurants, shopping, video rental ), and "transportation" (subway, bus lines, car rentals, car washes, gas stations, parking).
I would call this a guidebook for the Twitter generation. It gives you one quick line of description for each location; sometimes humorous, sometimes....well, useless. There is a one sentence description for a bar which all that it mentions is that it had a really big TV. I noticed some absences that I would point out if I was showing people around. Perhaps the book is not sold at Brookline Booksmith. Hence the absence of its entry and yet the New England Comics across and a little ways down the street gets a mention.
