What does textbook mean?
A textbook is a formal reference or instructional book that presents the basic principles, terminology, and ideas of a subject in an organized way. It is commonly used by students, teachers, and others seeking a dependable introduction or a concise account of a field. The word has also developed a figurative meaning: a “textbook example” or “textbook case” is one that displays every characteristic of a particular type, often so clearly that it seems almost exaggerated. In this figurative use, textbook can suggest either ideal clarity or a predictable failure. As an adjective, it is commonly used before words such as example, case, and approach. The term is familiar in British and American English and generally has a neutral educational meaning when referring to the book itself.
A book that gives an organized introduction to a subject and is intended for study or reference.

Etymology of textbook
