Strictly speaking, photocopying is different from copying, it should be the photo processing of the original, which is different from copying and piracy, and there are conceptual differences.
After obtaining the authorization to photocopy this book, copy the whole book completely according to the original book of the original publishing house, and then publish it in the name of the original publishing house, and indicate that it is a "photocopy".
The reason for using photocopies can be summarized as follows: it is too expensive to buy other people's original books. In order to save money, we completely copied other people's books after obtaining the copyright authorization from others, and marked the copyright as the original publishing house. Most of the photocopies are English books or ancient books.
As the picture shows, there is a difference between photocopying and copying.
Photocopy is a complete copy of the original! Copyright is still the copyright of the original! Because local printing can save a lot of money, the price is much cheaper than buying the original book (sometimes it's just different currency units)!
