Massachusetts, properly known as the Commonwealth of Massachusetts and nicknamed The Bay State, is one of the most history-rich states in the Union. Massachusetts was the first New England state to be settled — the Pilgrims founded Plymouth, Boston and Salem — and was also the site of the first shots to be fired in America’s Revolutionary War. Today, Massachusetts is a socially progressive state with an economy based on agriculture (Massachusetts is the nation’s second biggest producer of cranberries), manufacturing, health care and financial services. Higher education is also important with more than 40 colleges and universities in Boston alone, including the Harvard business and medical schools. CityBook.com has comprehensive online business listings for all 50 cities and 300 towns in Massachusetts. This includes online yellow pages for all Massachusetts cities with populations of more than 100,000 — Boston, Worcester, Springfield, Lowell, and Cambridge. These business yellow pages are an excellent resource for residents, as well anyone living out of state, trying to make business connections or find a doctor, real estate broker, home mortgage lender or other service provider.
