Article: There are a lot of public libraries in Britain. These libraries have more than one hundred and fifteen million books, not including those libraries of public schools. Public libraries not only lend books, music records but also help children, patients in hospitals and others to get special play readings, film shows and so on. 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. It has nearly every magazine, newspaper and book published in Britain and other parts across the world.
Answer: 10,000,000 or less.
Solution: How many books are there in the British Library?
Why? In the Article, 10,000,000 is mentioned for the number of books available in the British Library, so this is a good question.

New input: Article: Call it what you will--coincidence,fortune,luck or even fate--sometimes events combine together to show us that this is indeed a very small world.We've probably all had at least one experience where we've said "What a coincidence!" because there's no logical explanation for what has happened.Take the following stories from writer Lorri Benedik as examples: My friend,Emma Daniels,spent the summer of 1974 travelling in Israel.During her month-long stay in Jerusalem she frequented a cafe called Chocolate Soup.It was run by two men,one of whom,Alex,was a former Montrealer .One morning when Emma went in for coffee,while chatting with her new friend Alex,she mentioned that she had just finished the book she was reading and had nothing else to read.Alex said he had a fabulous book she might like,and that he'd be happy to lend it to her.As he lived just above the cafe,he quickly ran up to get it.The book he handed to Emma just minutes later was Markings,a book of spiritual writings by former Secretary-General of the United Nations Dag Hammarskjld. Emma had never read it,nor had she ever purchased a copy.But when she opened it up,she was _ to see her own name and address inside the cover,in her own handwriting.It turned out that the summer before,at a concert back in Montreal,Emma had met a Californian who was in town visiting friends.They decided to exchange addresses,but neither of them had any paper.The man had opened up a book he was carrying in his backpack and asked Emma to write her name and address inside.When he returned to California,he left the book behind in Montreal,and his friend Alex kept it.When Alex later relocated to Jerusalem,he took the now-treasured book along. Then there was the time that my husband voluntarily answered the phone at my parents' house,something he has never done in more than a dozen years of visiting them almost every weekend.But this time he got up from the dinner table,without being asked,when the phone rang.He was gone for quite a while and was quite pale when he returned to the dining room.It was a wrong number,he told us,but he had recognized the voice.It was his estranged sister,with whom he hadn't spoken in years.
Answer: Emma Daniels and the Californian kept in touch with each other by writing letters.
