1, the book you read must be your own. Don't scribble books in the library or books borrowed by others.
2. The meaning of each symbol should be fixed and cannot be changed at will.
3. Don't make too many symbols. If the whole page is circled, crossed and all become the focus, that is to say, without the focus, the symbol loses its meaning.
4. Be clean and tidy. Don't make the book so dirty that you can't read the original clearly.

Skills:
1. Copy selectively: Write down the most useful and enlightening contents in the text, and every copied note should be "few but precise". "Less" means fewer words, and "essence" means grasping the main points of content.
2. Be loyal to the original: There is a passage in the book that we think is quite good and want to copy it down. When copying, I feel that one word is awkward to use, so I use another word instead, which is not good. Since it is an excerpt, it is necessary to copy it according to the author's writing, not only the words and phrases can not be changed, but also the punctuation marks can not be changed. In a paragraph, words that don't need to be extracted before, after and in the middle can be represented by ellipsis.
3, to indicate the source: each material should indicate which page of the book it was copied from and who the author is. If you copied it in a newspaper or magazine, you should write down the name and date of the newspaper or magazine. Also indicate the title and author of the article. This is convenient for future use.
