Oxford ⁱ/ˈɒksfəd/ is a city in central southern England, the home of the University of Oxford. The city is the county town of Oxfordshire, and forms a district within the county. It has a population of just under 165,000, of whom 153,900 live within the district boundary. It lies about 50 miles (80 km) north-west of London. The rivers Cherwell and Thames (also sometimes known as the Isis locally) run through Oxford and meet south of the city centre.

Oxford has a diverse economic base. Its industries include motor manufacturing, education, publishing and a large number of information technology and science-based businesses.

Buildings in Oxford demonstrate an example of every English architectural period since the arrival of the Saxons, including the iconic, mid-18th century Radcliffe Camera. Oxford is known as the "city of dreaming spires", a term coined by poet Matthew Arnold in reference to the harmonious architecture of Oxford's university buildings. The University of Oxford is the oldest university in the English-speaking world.

A guide book is a book for tourists or travelers that provides details about a geographic location, tourist destination, or itinerary. It is the written equivalent of a tour guide. Many travel guides now take the form of travel websites rather than printed books.

It will usually include details such as phone numbers, addresses, prices and reviews of hotels and other lodgings, restaurants, and activities. Maps of varying detail are often included. Sometimes historical and cultural information is also provided. Different guide books may focus on different aspects of travel, from adventure travel to relaxation, or be aimed at travelers with larger or smaller travel budgets, or focus on the particular interests and concerns of certain groups such as sexual orientation or dietary restrictions. Guide books are generally intended to be used in conjunction with actual travel, although simply enjoying a guide book with little or no intention of visiting may be referred to as "armchair tourism".

The periplus was an itinerary from landmark to landmark of the ports along a coast, a forerunner of the guide. A periplus such as the Periplus of the Erythraean Sea was a manuscript document that listed, in order, the ports and coastal landmarks, with approximate intervening distances, that the captain of a vessel could expect to find along a shore. It served the same purpose as the later Roman itinerarium of road stops.
