Extended data
Publishing is a social activity to deeply develop existing works. Publishing is not the development of original information, but the development of ready-made works.
The task of accepting original information, reducing it to knowledge and forming knowledge products has been completed by the author, or mainly by the author. The formation process of existing works belongs to the author's labor process, not to publishing activities. Writers create, painters sketch, musicians compose, etc. It's not published, that's why.
Publishing is the process of editing and processing the original work to make it have published content suitable for readers' consumption. Although the publishing process is not the main formation process of knowledge information, it is a process of selecting knowledge information system, which is carried out according to the requirements suitable for readers' consumption.
Moreover, according to the same requirements, the knowledge information in the selected works is sorted, supplemented, refreshed and improved, that is, the original works are edited and processed through editing. Paper money is not a publication, printing paper money is not a publishing activity, or it is because the original work has not been edited and processed, thus lacking knowledge and information content for readers to consume.
