Generally speaking, if there are many pages in the book, sewing and binding will be adopted, because the firmness and flip resistance will be better and the service life will be longer; However, if it is wireless binding, it is easy to have loose pages and broken glue.

Just pay attention when buying books. See if it's published by an ordinary publishing house. You can also observe the hardness of the glue. If it is soft, it will last for a long time. Now the plastic version can be kept for a long time, as long as it is not pulled hard, it will not come apart. There seem to be fewer books in the thread now. Moreover, I personally feel that thread-bound books are not easy to preserve and are prone to wrinkling.
