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: Dear Mr Rupp, The day I met you was the first day of high school. We liked each other immediately. You gave me a lot of advice over the next four years, like how I should get my ass to Berkeley where I belonged. I'm still there, by the way. I wish you were still around, too. I remember your laugh, which would start with a rough guffaw and end with a hacking smoker's cough that would make even the most rebellious teenager swear to lay off the cigarettes. I remember the way you didn't lower your standards, yet still refused to give up on us. You were tough on us, and we were tough on you. Love is tough sometimes. The last time I wrote you a letter, it was 2005---four years after I graduated. I had just become a teacher, like you, and it had given me a new appreciation for the work you did with countless high school students over the years. It's hard to say what I'll miss the most about you. There are simply too many memories to sort through those four years, and it hurts to think you'll never read this letter. I want to believe that you knew how much you meant to your family, your students, your community, and your colleagues, but that would be a lot of realization to handle, even for you. You changed the lives of everyone around you. Even now, you are reminding me to cherish life and its brevity and beauty, and to tell the people I love how much they mean to me before it is too late. Dear teacher, dear mentor, and dear friend----I miss you and all that is about you. God bless you in Heaven. To infinity and beyond, Teresea
