I need to find a specific book in the library. Can you help me with the steps to locate it? The book I am looking for is titled [book_title] by [author_name]. Please provide a detailed process, including how to use the library catalog and what to do once I find the book's location. Your response should contain at least 5 sentences and at least 2 placeholders represented by square brackets, such as [address]. Highlight at least 2 sections in your answer with markdown, i.e. *highlighted section*. Include a postscript starting with *P.S.*.
