Oct. AD, B00I Dear Jones, I am writing to ask for our help in lending me a book. Recently I’ve been busy preparing my graduate thesis, and therefore have been reading and researching numerous books and other references. One of the books that my advisor believes to be particularly relevant to my thesis is called The Legal System in Society. Unfortunately I have been unable to find it at the library or in any bookstores. I heard you have a large collection of books about Law. Do you happen to have this book If so, may I borrow it I promise to take good care of it and ill return it to you within three days. Thank you very much. I hope to hear from you soon. Yours sincerely, Li Ming
