How to identify whether the book I bought is genuine?

(Transfer) There are two main types of pirated books based on their printing quality:

1. Low-end pirated books. The overall printing quality is poor and easy to identify. The performance is as follows: poor paper use (paper is thin, yellowish, and gray), uneven ink color, hue deviation, inaccurate overprinting, blurry images, and often tape on the edges of graphics and text. Traces or imposition marks, the finished product is not cut squarely, the binding quality is poor (there are many missing lines, wrong pages and other quality problems), and there are many errors in text and punctuation marks (some typos can reach more than ten in one code), and wrong sentences Continuous articles.

2. High-end pirated books. The overall printing quality is high, not much different from the original book, and difficult to distinguish. The performance is as follows: better paper, more uniform ink color, better hue, more accurate overprinting, clearer image layers, squarer cutting of the finished product, and better binding quality. It's better and has fewer typographical errors.

Generally speaking, low-end pirated books are printed by small printing plants or underground printing plants using low-end equipment. They are produced by some small pirated booksellers in a piecemeal and guerrilla operation. High-end pirated books are printed by relatively powerful pirate booksellers using higher-end equipment, and some even use imported equipment.

It can be said that the current pirated books are still mainly low-end pirated books, and this situation will continue for quite some time, but we should also see a small number of high-end pirated books. Therefore, we should not simply think that "if the printing quality is good, it is not a pirated book, and if the printing quality is poor, it is a pirated book", nor should we simply think that "pirated books must be cheaper than genuine books".

The most accurate way to identify pirated books is to compare the paper, printing, and content with genuine books from publishers of the same edition, and also check the copyright page of the book (the copyright page of the genuine book). The copyright page must include the book's in-print cataloging data, name and address of the publishing unit, book format, edition, etc.) and whether the international standard book number and barcode mark are complete and clear. If necessary, consult the publisher of the genuine book. Of course, if there is an anti-counterfeiting mark, it is still not difficult to identify.

1. Quality:

1. Carefully review the appearance of the book. Specifically: the first-instance cover. Compared with genuine books, the covers of pirated books often have incorrect colors. They are either so dark and listless, or so bright and voluptuous, and the colors are often mixed. As long as you compare frequently, the difference is not difficult to distinguish. Second, look at the binding. According to publishing industry convention, for a genuine book with more than 200 pages, wire binding should be abandoned and wire binding should be used instead of thread binding, plastic thread binding or perfect binding. Due to limitations of printing and binding equipment or to reduce costs, pirates still commonly use wire binding for pirated books with more than 300 or 400 pages. Third visit to the printing house. Each publishing house has a number of fixed printing users, and each printing house also has its own characteristics in terms of paper, ink, and printing. If you pay attention to this, it will help to identify pirated books. Fourth, look at the paper. The book should be printed on both sides. If the paper is too thin, it will be easily mixed with ink, causing the writing to be blurred and difficult to read. Therefore, except for dictionaries, the paper used for genuine books is 52 grams and above. Once you encounter a book with thin paper and the writing on the other side is exposed, you must be careful.

2. Review the content of the book. There are three symptoms in the internal text of pirated books: first, there are many typos, aliases, missing characters, word extensions, and incorrect sentences; second, the typesetting is often not neat, either sparse or dense, and it is visually astringent; third, it looks like a copy. Some pirated books are not typed separately, but are copied from the original book. Although this can avoid text errors and typesetting ugliness, there are many ink dots on the paper and the handwriting tends to be puffy and looks like it was drilled out of a copy machine. Come out with a copy. In fact, no matter how fake it is, there is always a gap between pirated books and genuine books. Therefore, it is best to shop around when buying books.

3. Pay attention to book publishing information. Such as publisher, ISBN, edition, etc. The reason why I dared to conclude that the "Mountain House Notes" I saw was a pirated book was not just limited to the many typos. Yu Qiuyu's "Notes on Mountain Dwelling" was originally published in "Harvest" in Shanghai, and his "Sorry for Shanxi" and other chapters have been included in Yu's "Fragments of Civilization" (Chunfeng Literature and Art Publishing House) and "Qiu Yu Prose" (Zhejiang Literature and Art Publishing House) Edition) and other selected editions.

For fear of being overpriced by readers, Yu Qiuyu has always refused to collect and publish "Notes on Mountain Dwelling" in mainland China (the book was published in a traditional Chinese vertical version in Taiwan in 1995).

2. Price: Genuine books are all priced uniformly by relevant departments, so the purchase discounts of genuine booksellers are relatively high, and the purchase discounts are almost the same. Therefore, buyers are requested to be sure to buy books in online bookstores. For some extremely low-priced books, be sure to inquire before buying them. Don’t be greedy for cheap.

3. When buying genuine books, it is best to choose some relatively large and reputable online bookstores, because these sellers generally have more legitimate purchase channels. If you are not sure...gt；gt;

How can you tell whether a book is genuine?

1. To distinguish between genuine and pirated books, you must first check whether there are anti-counterfeiting marks. Generally, genuine books have them.

2. Another thing is to touch the edge of the paper. Pirated books require simple workmanship and often have uneven edges.

3. The next step is to flip through and listen. The sound of the paper in genuine books is musical (that is, there is no noise). Pirated books often have a lot of noise. If the musical sound is expressed as "hiss", then the sound of the paper is pirated. The sound is "hiss, hiss, hiss, hiss".

4. Take another look and find out that pirated books often use low-quality or even fake ink in order to achieve low workmanship costs. These inks often contain excessive amounts of lead, and lead can make people stupid! The smell of these inks is very strong. If you smell a strange smell, it is likely to be low-quality or even fake ink! (Don’t smell it for too long!)

5. If you can’t smell it, just touch it. Use your fingers to wipe the area with words 3-5 times with appropriate force. If there is discoloration, it is likely to be inferior quality or even fake ink.

How to identify whether a book is genuine?

Hello.

There are many ways to identify pirated books. Generally speaking, it can be viewed from the following aspects.

Take a look at the paper. The paper of pirated books has a thin feel, is usually yellowish, gray, and has poor elasticity. If you tear a small hole, you will find that the break is smooth, while the paper of genuine books has a thicker feel, is whitish, and generally has a higher wood pulp content. It can be found that the fracture is not smooth and has trace amounts of fibers.

Second look at the printing. The pictures and text in pirated books are usually blurred or even distorted; there are often traces of tape, scissor cutting or other imposition marks, and the pictures and text are often bent; pirated books usually do not edit the edition, so the various traces produced in the plate-making process are obvious; piracy The inner ink color of the book is uneven throughout the book. There are no gaps between thick strokes, and light strokes can be disconnected, making it look like a double image.

Look at the content three times. There are many errors in text, words, sentences, and punctuation marks in pirated books, and some typos can reach more than ten on a page (the typo rate of genuine books is generally no more than one in 10,000).

How to check whether a book is genuine and how to check CIP

To check CIP, you can go to the website of the General Administration of Press and Publication or the official website of the Chinese Version Library. General Administration of Press and Publication → Service → Convenient inquiry → News and publication product inquiry → CIP data verification number verification → Enter the year, six-digit verification number, and verification code to query. The starting year of this query data is from September 2009 to September 2013. If the query cannot be found, there is another query entry.

In addition, there is also a query entrance on the right side of the home page of the official website of the Chinese version of the library. ——Guru Culture Media Book Publishing.

How to judge whether a book is original and how to check whether the book you purchased is genuine

Bertelsmann was once accused of selling pirated CDs, but all the books it sold were genuine.

As for the book "Five Star Hotel" you mentioned! Because the paper produced by the publisher is not very good, this book appears to be a pirated copy. But it is actually an absolutely genuine book. You can go to Xinhua Bookstore or some large bookstores to check it out. It's all like that.

How to judge whether a book is pirated?

Visual inspection of the cover

First look at the cover. You can check the color, clarity, paper quality of the cover, and the book. Observe aspects such as binding. Specifically, pirated books generally have brightly colored covers, murky writing, thin cover paper, and overflowing glue from offset printing. Hardcover books may lack plugging cloth (plugging cloth: a long strip of silk-cotton cloth with a rounded end) Tightly woven gussets are glued to both ends of the spine to protect the spine cut and increase the beauty of the book) or without front and rear lining.

Look at the back cover to see if there is a barcode and pricing. If there is no barcode, it must be a pirated book. (See below for special circumstances)

Review the text

Of course, everyone knows to open a page and read the previous paragraph carefully. If you find many typos, you can basically judge. The book in your hand is a pirated copy. This is the method used by most people to identify pirated books, and it is also the most intuitive method.

In fact, there are many aspects. For example, whether the font size of the chapter titles is uniform, whether the handwriting is clear, and whether the paper used in the book blocks is suspiciously thin (except for dictionaries and art books, the book blocks mostly use writing paper of about 55 grams.) There are also some photocopied pirated books Although there are no other words, it is inevitable that there will be inconsistencies in the density of the layout, or the distance between the sky and the ground will not be uniform.

Take a closer look at the copyright page

The copyright page is usually on the back of the title page, or sometimes at the end of the text, with the Catalog-in-Publication (CIP) data printed on it. A relatively simple thing is to check whether the International Standard Book Number (ISBN) on the copyright page is consistent with the one above the barcode on the back cover. If it is inconsistent, it usually means it is pirated. Some low-quality pirated books simply don’t have a copyright page. Exclude the situation where the copyright page of a set of books is divided into several volumes, and the barcode of the first volume is in the last volume or both in the last volume. However, at this time, the set of books must have the same title and book number (ISBN).

Accumulating experience

The accumulated experience here refers to experience in copyright. Many pirated books use the names of publishers such as Inner Mongolia Publishing House and Ximin Publishing House, which are remote places where information is not easily conveyed. In fact, these publishing houses generally only publish some books translated from Chinese into minority languages, and due to their relatively backward culture, the general categories of books they publish are very limited. When you see the famous books and proverbs from these publishers, you have to be extra careful.

Pirated booksellers do not know much about copyright information, and it is often the case that a set of pirated books uses the names of several publishers. There is also a whole set of books with different titles using the same ISBN, which are illegal even if they are not pirated books.

For those who often buy books and read, it is best to order a newspaper such as "Wenhui Reading Weekly". Reading newspapers regularly can not only learn about new books, but also learn some copyright information. That way you won't be in Harry Potter. Before "Potter" was introduced, I thought that the Chinese translation of "Ha" I bought was genuine. Of course, you can also go to some cultural websites to get information. I personally recommend Sanshi Culture Communication Network.

Buy books through formal channels

You can rest assured when buying books at Xinhua Bookstore, bookstores or branded private bookstores such as Sile Bookstore.

Some publishing houses have also adopted some anti-piracy measures, such as laser anti-counterfeiting marks, embossed book titles, title page watermarks, interleaved color pages, etc.

That’s it, I’ll add more when I think of it later. If you have any other personal experiences, remember to share them with everyone! cache.baidu/...=baidu

Look at the quality of the paper. The quality of pirated copies is very poor, and some have many errors. The pages of the book are torn. Now some of the more expensive books have anti-counterfeiting marks. You can scan the QR code

How to check whether the book is genuine

A. Look at the paper: the genuine version uses light offset paper, which is light in weight; the non-genuine version uses light-weight offset paper to save costs. Will use ordinary paper: writing paper or offset paper! Identification method: Find a book with a similar number of pages and the genuine book. Use your left and right hands to weigh it and you will clearly feel that the genuine one is lighter! For version A, you can only look at the paper used. B. Format: There is an item on the copyright page of the book (for example: 640*960 mm 1/16), of which 16 means the format of the book. The genuine one is 16 karat. The non-genuine version may be 32 karat, which is a little shorter than the genuine one. C. Price comparison: The price of genuine books is higher. In order to attract shopping friends to patronize, I sell some books at the purchase price (50-40% off). Below that price, it's possible. If the seller sells the A version of the book as genuine, I have no choice but to wait until you receive the book and use some genuine books for comparison.
