Binding methods refer to the various techniques used to hold together the pages of a book or document. Common types include saddle stitching, where folded sheets are stapled along the spine, and perfect binding, which involves gluing the pages to a flexible cover. Each method has its own advantages, such as cost-effectiveness or durability, depending on the intended use of the publication. Another popular binding method is spiral binding, which uses a plastic or metal coil to keep pages together, allowing them to lay flat when open. Wire binding is similar but uses a wire loop instead. These methods are often chosen for notebooks and reports due to their flexibility and ease of use.
