The first public libraries were founded in about the year 1850. Today's public libraries usually have a reading-room, a lending room and a reference room. The greatest and most famous library in Britain is that of the British Library in London. It was founded in 1973 and has over 10, 000, 000 books.

New input: Article: When you are traveling in Thailand,which means of transport is the best choice? You can rent a variety of motorbikes or bikes in Thailand.It seems to be very popular in most of the beaches and islands along the places in the north.The most popular bikes are the little 125 cc Honda Dream which you can get for about 150 baht a day or as little as 3,000 baht per month,making it the cheapest way to tour Thailand for the people from other countries. Sometimes you will have to go somewhere by taxi.When you are in cities in Thailand,especially in Bangkok,always remember to get a taxi that is going on the roads.Some drivers outside hotels refuse to use the milometer .They will ask a price which is several times the price when they use the meter! The quality of the roads in Thailand is generally pretty good,so renting cars is another way to get around.The big car rental companies may offer you slightly older cars at a very reasonable price.It is a little surprising considering that the cost of buying a car in Thailand is more than that in the West.Petrol is also reasonably priced in Thailand,more expensive than American prices,but much cheaper than what is paid in Europe.In the past,Bangkok could be a difficult place to drive in--signs were generally in Thai only,making it a hard job to find exactly where you were by looking around.But now,the situation is improved.In a lot of places,even the farthest corners of the country,street signs are in both Thai and English.
Answer: To take a taxi driving on the road.
