First, genuine books.
As we all know, genuine books are generally called genuine books after being printed and published by publishing houses or other copyright organizations, or after being legally authorized by authors or copyrights. If books are circulated in the market without the consent of the author or the legal authorization of the corresponding copyright agency, these books will be gone and will not have certain reliability. Therefore, such books are not genuine books. Generally, genuine books provide books with much better feeling and quality, and will have the signature and quality of the correspondent.
Second, books without copyright.
Books without copyright are not genuine books and can be called pirated books. Pirated books are generally called pirated books, and books without the authorization of the original author or publisher are called pirated books. Moreover, the cover of pirated books is generally bright in color, but the handwriting is turbid and the typesetting is not very clear, especially the cover paper is thin and the workmanship is rough. In fact, many people who buy books can check whether they are pirated books through this aspect, and pirated books can indeed be found in. Third, pay attention
You must pay attention to this. As some people who love reading, try to buy genuine books. If you blindly choose pirated books and think they are cheap or durable, it is actually a wrong way. After all, many knowledge points or transmission methods in pirated books are probably not very correct, and it is not true to see pirated books. When you read a book, you will fall short when you find that the content of the book is completely different from the original.
