WHY DOES IT MATTER?

1 reason

Inferior products

Counterfeit books have a lack of quality comparing to legitimate textbooks. They are made of cheap materials with ‘grainy’ images and badly printed text.
2 reason

Harm to the educational system

Counterfeit items take money away from publishers and cause loss of authors’ royalty. Revenue decrease leads to the termination of the new book’s publication.
3 reason

Low value

Crucial content, cases, access code to the online material may be missing in counterfeit books. Also, different pagination may lead to confusion while studying.
