1. Author information: First, you need to find the author information of the document. This is usually at the beginning or end of the document. If the author's information is not clear, you can try to use online database or library resources to find it. Once the author information is found, it should be accurately recorded, including the author's full name, professional title and so on.
2. Date of publication: The date of publication is usually on the cover or copyright page of the document. You need to find this date and record it according to the standard date format (for example, YYYY-MM-DD). If the publication date is not clear, you can try to find the first edition date or acceptance date of the document.
3. Title and publication information: In addition to the author and publication date, the title and publication information of the document should also be recorded. The title should be accurate, and the publishing information should include the name and location of the publishing house.
4. Reference format: When sorting out documents, you need to mark information according to a specific reference format. Common citation formats are APA, MLA, Chicago, etc. You should choose a format and always tag information according to this format.
5. Use reference management software: If you have a lot of documents to organize, you can consider using reference management software, such as EndNote and Zotero. These softwares can help you automatically extract and sort out literature information, greatly improving your efficiency.
Generally speaking, it takes some time and patience to correctly mark the author, publication date and other information, but it is very worthwhile. This can not only help you better understand and remember the literature, but also improve your academic writing and research ability.
