Look at the cover first, which can be observed from the aspects of color, clarity, quality of cover paper, book binding and so on. Specifically, pirated books generally have bright cover colors and muddy handwriting. The cover paper is thin and the offset glue overflows. Hardcover books may lack a plug cloth (plug cloth: silk cotton strip cloth with a tightly woven ridge at one end). Stick it on both ends of the spine to protect the spine incision and increase the aesthetic feeling of the book. ) or without front and rear ring linings.

See if there is a bar code and pricing on the back cover. If there is no barcode, it must be a pirated book. (See below for special circumstances)

Audit text

Of course, as we all know, you can turn over a page and read a paragraph carefully. If you find many others, you can basically judge that the book in your hand is pirated. This is the method that most people are using to identify pirated books, and it is also the most intuitive method.

There are actually many aspects. For example, whether the font size of chapter titles is uniform, whether the handwriting is clear, and whether the book block paper is suspiciously thin (except dictionaries and art books, the writing paper used for book blocks is about 55 grams). There are also some photocopied pirated books. Although there are no other characters, it is inevitable that the typesetting density is inconsistent or the distance between the head and the foot is not uniform.

Look at the copyright page carefully

The copyright page is usually on the back of the title page, or at the end of the text, with CIP data printed on it. It is relatively simple to check whether the ISBN of the copyright page is consistent with the barcode on the back cover, and the inconsistency is generally piracy. There are also inferior pirated books with no copyright pages at all. Exclude the case that the copyright page of a set of books is divided into several volumes, and the barcode is in the first volume or the last volume, but at this time the set of books must have the same title and ISBN.

gather experience

The accumulated experience here refers to the experience about copyright. Many pirated books steal the names of remote publishing houses such as Inner Mongolia Publishing House and people in Xizang Publishing House, making it difficult to transmit information. In fact, these publishing houses generally only publish books translated from Chinese into minority languages, and the total categories of books published are very limited because of the relatively backward culture. Be extra careful when you see the famous books, proverbs and quips of these publishing houses.

Pirated booksellers don't know much about copyright information, and pirated books often use the names of several publishers. There is also a whole set of books with different titles using the same book number. These books are illegal, if not pirated.

People who often buy books had better order a newspaper, such as Wen Hui Reading Weekly. Reading newspapers often can not only help you learn about new books, but also some copyright information. So you won't feel that the Chinese version of Harry Potter you bought is genuine before it is introduced. Naturally, you can also go to some cultural networks to get information. I personally recommend Shisan Culture Communication Network.

Buy books through formal channels

You can rest assured that you can buy books in private bookstores such as Xinhua Bookstore, Bookstore or Thinking Music Bookstore.

Some publishers have also taken some anti-piracy measures, such as laser anti-counterfeiting marking, book title embossing, title page watermarking, sandwich color pages and so on.

That's all. I'll add it later. If you have any personal experience, remember to share it with everyone!
