A notebook (notepad, writing pad, drawing pad, legal pad) is a small book or binder of paper pages, often ruled, used for purposes such as recording notes or memoranda, writing, drawing or scrapbooking.

Notebooks used for drawing and scrapbooking are usually blank. Notebooks for writing usually have some kind of printing on the writing material, if only lines to align writing or facilitate certain kinds of drawing. Inventor’s notebooks have page numbers preprinted to support priority claims.
