1. Publishers may have deleted the original works in order to control the quantity and pricing of books. The deleted content may include chapters, illustrations, words and other parts, resulting in the final published version of the content is incomplete.
2. In addition, there may be differences between different versions of entomology. Entomology is a book composed of many volumes, and the number of chapters in each volume may be different. So even if the publishing house doesn't cut it, different versions of entomology may have differences in content integrity.
In addition, the translation process may also lead to the loss of the original content. The translated version may be different from the original due to factors such as understanding and language conversion in the translation process.
In a word, the incompleteness of Entomology published by People's Education Press may be due to the influence of deletion, edition difference and translation.
