Babies like to chew on books. Toddlers have difficulty turning pages without tearing them and will use any handy crayon or marker to adorn books. Make sure that small children have books strong enough to withstand their attention and make reading an altogether time. Leave repairs to the experts. Adhesive tape turns brown with age and stains the paper.
Libraries have special repair methods that last a long time.
Never use duct tape or electrical tape or any other household material to repair a library book. You will cause even more damage. Use a photocopier when you want to keep something from a library book or magazine. Torn out pages take time and money to replace, and the binding of the book is weakened by page loss. Often more pages are loosened and will fall out soon.
