Books are the ladder of our progress and an indispensable part of our lives. However, I think you must also have bought pirated books, especially students' study books, not only misspelled characters, but also typesetting disorder, seriously affecting children's learning and use. So, how to distinguish between genuine and pirated books? The following small series will simply talk about their own identification methods.
Demo books: Legal and pirated
The cover color is different. The pirated titles are dark and the legitimate ones are bright.
The size and weight are different. Pirated books written size can be large or small, the size is not uniform, the back of the book is generally marked with the specifications of the book, accurate to the millimeter (this is the specifications of the legitimate book), so you can use a ruler to measure to see whether the size of the book meets the standard. And the paper of the pirated book is worse, so it is generally thinner than the legitimate book, so the same book, the pirated book will be thinner.
Paper is different: pirated books paper check, touch by hand, very rough, some pirated books fold up with creases, and genuine books paper uniform, good quality.
Content: There will be almost no typographical errors and misspellings in legitimate books, pirated books generally have misspellings and typographical problems, and the printing quality is poor, and sometimes there will be ambiguity.
The smell is different: the legitimate book is very strong ink or paper smell, and the pirated book pungent smell, mainly the lead content is high, the smell is large, long-term use will have an adverse effect on the body.
The price is not the same: because the cost of legitimate edition is high, and some also contain copyright fees, and the cost of piracy is low, so the discount of legitimate edition is low, and the price of pirated edition is uncertain, sometimes too low (except used books).
Summary: (1) Look at the cover color. (2) Look at size and weight. (3) Look at paper. (4) Look at the content. (5) Smell. (6) Look at the price. In short, the harm of piracy is great, its lead content is excessive, there are many misspelled characters, there are double shadows affecting eyesight, and the layout is confused and crowded, so it is recommended that you must buy genuine books.
Tip 1: It is recommended that you must buy genuine books. Especially children's teaching books, otherwise it will affect children's physical health and learning.
Tip 2: With the progress of science and technology, the quality of pirated books is getting better and better, it is difficult to distinguish, I hope you can carefully identify according to the above method.
