A notebook is a blank book that you can write in. Students often carry notebooks, where they can take notes (and doodle). The pages in a notebook are often lined, so that you can write neatly. ... Notebooks can be bound like books, or with a spiral metal or plastic binding, or consist of loose pages in a three-ring binder.
A notebook (also known as a notepad, writing pad, drawing pad, or legal pad) is a book or stack of paper pages that are often ruled and used for purposes such as recording notes or memoranda, other writing, drawing or scrapbooking.
