1) Description of the monograph "Page number". When a monograph is cited as a citation document, the page number of the cited information, that is, the "citation page number", is an essential description element; Only when the full text of the monograph is cited as a reading document, the page number is not recorded. In practice, it is often seen that the monograph as a cited document lacks the recording error of "citation page number"

2) Description of "page number" of articles separated from periodicals. The new standard stipulates: "All articles separated from periodicals should be marked with their year, volume, issue and page number after the title. The page number of the reading reference describes the starting and ending pages of the article, and the page number of the cited reference describes the page where the cited information is located. " It can be seen that it is incorrect to record the page numbers of articles separated from periodicals in current sci-tech books and periodicals, or to mark the beginning and end pages without distinguishing between two types of references. For the sake of brevity, it is appropriate to mark the start page of the reading document.

3) Description of the "page number" of the literature separated from the monograph. Monographs here include compilation and meeting minutes, and separated documents refer to "documents with independent titles separated from the whole information resources". Just like the page numbers of articles in periodicals, the page numbers of documents in compilation and meeting minutes should also be recorded. When recording, two types of documents should also be distinguished. For the cited documents, the page where the cited information is located should be marked, and for the read documents, the starting page or the starting page should be marked. In editing practice, it is not standard to label the files separated from the assembly and meeting minutes without page numbers, or to label the start and end pages in disorder.
