How to cover a book properly
For books with a very soft cover, we can add non-adhesive plastic covers, a little bit thick in order to give it stiffness and to protect it from possible damage. If the plastic is not thick enough, it will not comply with its function and it will feel unpleasant to the touch with the heat. We have to avoid the adhesive tape that fastens the cover to touch the book.
For those with a hard cover we can use paper, preferably without ink in order to prevent from getting ink stains on the book or our hands. This way we will be able to use this space to take notes on the work.
We can reutilize the covers for other books, or as drafts (the ones made out of paper).
