Loose-Leaf Books (Books & Booklets)
Loose-leaf is also perfect for documentation that updates frequently. It's much cheaper to produce and distribute only those sections that have changed. Leaving a book in loose-leaf format offers flexibility to reorganize the book, or pull-out the section you are currently working on. Loose-leaf in sets is popular for business forms. Shrink-wrapping in convenient, easy-to-handle packs provides protection and the packs are much easier to store and distribute.
