Write a title at the beginning, that is, what kind of content the selected material belongs to, or it can be expressed in code. Fill in "categories": such as "famous sayings", "the way to success", "learning from the sea", "science and technology exhibition", "collecting shells from the sea", "moral cultivation" and "communication art". Fill in "No.":Fill in the serial number. Three, fill in the "title": there are two ways to fill in, one is to fill in the original title; The other is the author's own proposition, which is mainly based on the summary of the abstract content.

Extract the middle text. This is the main part of the card. Pay attention to three points when writing the text: be sure to write clearly; Pick the essence, not too long; Done. The copied content must be comprehensive and complete, and it is not allowed to omit, copy more, and not to change the original intention, especially the foreign language document cards. Write every letter clearly.

Finally, indicate the source. For the citation of books, the title, periodical name, article name, author, publishing house, publication date and page number should be indicated (page by page, if a self-translated work is cited, the original foreign language should be indicated). It shows that the quotation is reliable and can be verified. Citation of periodicals and newspapers should indicate the title of the article, the author, the name of the magazine or newspaper. Magazines should write down the year, volume, issue and page, and newspapers should write down the year, month and day (even the first edition). In the last line, the abstractor should specify the abstract time.

However, there are still a few points to emphasize:

First of all, the style of writing cards should be fixed. For example, the title of the information written on the card should be agreed in advance; There are also titles, which should be marked according to the classification of self-taught subjects. A headline can also be marked with several sub-categories, which requires learners to operate flexibly from the reality of self-study.

Secondly, there should be guidelines for titles and subcategories. There are too many cards to remember, so when you put them together, you should use a guide to classify them. The guide can be slightly higher than the card, with the destination category written on it.

Thirdly, after the card is selected, it is necessary to write "category", "title" and "number" in time to facilitate the search.

Finally, it needs to be emphasized that the source of information must be clearly stated one by one, and we must not be lazy. Some people only remember the content of the material when they teach themselves, omitting it or not writing it at all. If you miss these, you will not find the original text in the future, and all your previous efforts will be in vain.
