I'm sorry for any confusion, but "Account Books" are not a medical term and do not have a medical definition. An account book is a type of financial record-keeping tool used in various industries, including healthcare, to track income, expenses, and other financial transactions.
A book is not a medical term, but generally refers to a set of printed or written sheets of paper bound together that can contain a wide range of information including literature, research, educational content, and more, which may be utilized in the medical field for various purposes such as learning, reference, or patient education.
I'm sorry for any confusion, but "Book Selection" is not a term with a recognized medical definition in the field of healthcare or medicine. It might be related to literature or library science, where it refers to the process of choosing books for a collection based on various criteria such as relevance, quality, and diversity.
