One of the biggest differences between paperback and hardcover is the cover.

In terms of feel, the cover of paperback picture books is soft, that is, a thick layer of paper. The cover of hardcover picture books is mostly made of cardboard leather, cardboard cloth or other artificial composite materials, which has a strong texture, so the cover of hardcover books is often called book shell.

In terms of thickness, a book with the same title must be thinner in paperback than in hardcover.

Because the cost of paperback books is low, many pirated books are paperback.

Step 2 read paper

In order to save costs, pirated books usually use cheaper paper.

For example, the "Baby Bear" series, with a genuine cover of 250g coated paper, has very good gloss and bright color; Pirated books are made of cardboard, which feels dark and rough.

3. The format of reading books

For example, the information on the copyright pages of the runaway rabbit, pirated books and pirated books also says 24 quarts, which is actually much larger than 24 quarts.
