The New York public library is a very special place. Even though it is the busiest part of the city, it has grass and trees around it and benches for people to sit on.[4]However, it is the large rooms of the library that make it more unusual in the crowded New York. The roof of the main reading room is 51 feet high. Here a reader can sit and think and work in comfort. The library has over 30 million books and paintings. It owns one of the first copies of a Shakespeare play, a Bible printed in the 15 th century and a letter written by Columbus in which he tells of the findings of the New World. Every New Yorker can see and use the library’s riches free, but the cost of running the library has risen rapidly in the recent years and the library does not have enough money to continue its work.[5]In the past it was open every evening and also on Saturdays and Sundays. Now it is closed at those times to save money. The library is trying in every possible way to raise more money to meet its increasing costs. Well-known New York writers and artists are trying to help, so are the universities whose students use the library and the government of New York city and New York States. But the problem remains serious.[6]Yet a way must be found to save the public library because as one writer said, "The public library is the most important building in New York city, which contains all our knowledge.
