Book review is difficult to reflect your academic ability, only papers can do it.
Remember, anyone who recommends the core book review to you will tell you that it can be all-inclusive, that is, the core book review will send you money, and there is no quality at all. And your core is not to let anyone recognize you, but to prove yourself in the second interview. You go to the second interview site and show the book review to the tutor. You think the tutor doesn't know what's going on? Excuse me, is it useful or not? You can weigh it yourself.
No matter what use you have, don't believe the nonsense of those black-hearted intermediaries, and don't be fooled into sending core book reviews for the sake of good hair.
Core journals are the main journals of a certain discipline. Generally speaking, it refers to a professional periodical with a large amount of professional information and high quality, which can represent the development level of professional disciplines and is valued by readers of this discipline.
Relevant experts have found that the actual distribution of literature information sources has a core journal effect, that is, a large number of scientific papers in a certain profession are concentrated in a few scientific journals.
This phenomenon can be seen in many fields, for example, from the study of the world literature of physics in France's Signal Bulletin, it is found that 90% abstract items are only taken from 30% of all journals, and chemical abstracts can be extracted from 9% of all journals to 75% of all abstract items.
Therefore, in the era of literature information surge, the effect of core journals has been widely concerned by people. There are many ways to determine the core journals, and China generally makes comprehensive determination according to the following principles:
(1) Journals with a large number of articles (that is, the amount of documents published in this discipline).
(2) Journals with a large amount of secondary literature excerpts.
(3) Periodicals frequently cited by readers.
