According to library society of china's Library Standardization Guide, giving books refers to the behavior of individuals or units donating books to libraries or other institutions. When giving books, you don't need to count the printed sheets. Printing refers to the size and quantity of paper used in book printing, which is used to calculate the printing cost of books. When giving a book, the donor does not need to pay attention to the printing problem, just donate the book to the recipient. Therefore, books and gifts are not counted as printed copies.
