A notebook (also notepad printing, print notebook, writing pad, drawing pad, legal pad, etc.) is a book, usually of paper, of which various uses can be made, including writing, drawing, and scrapbooking. Notebooks can be distinguished along several dimensions and sub-dimensions. Variations of print notes that allow pages to be added, removed, and replaced are bound by rings, rods, or discs. In each of these systems, the pages are modified with perforations that facilitate the specific binding mechanism's ability to secure them. Such printed books bring people convenience and remind them of something important. For example,you can mark down the house chores in your household notebooks.
