- the pdf
When you read a book you probably use some sort of bookmark that will help you find the place you finished reading last. Folding down the corner, a piece pf paper or card, a special ornamental plastic that clips onto the pages, or a sticky coloured plastic. Whatever you use you find it necessary because we cannot always remember exactly where we left off. When we use a computer or tablet or such like we need something to help us find where we were last so that we can easily return to that place.
