Paper employment notice usually needs to include: magazine name, paper name, paper number, publication date, bookmark date, magazine seal, etc. If you need to pay, you will specify the details of the payment in the text or annex of the notice. Some only charge the printing fee, while others need to pay for production, mailing and auditing. It is necessary to face up to the fact that the fees of each magazine are different. The most direct way to identify the authenticity of the employment notice is to call the magazine and ask, and the magazine editor will tell you.
Some authors did not contribute to some journals, but received employment notices. This situation can basically be judged as fraud. Don't trust similar letters sent by some magazines, such as employment notices and award-winning notices, and send money to the other party. If you want to publish a paper in an official domestic journal, you should check whether the magazine indicates the unified domestic serial number. Official publications published within the territory of China should indicate the number of domestic unified continuous publications on the edition filing page, that is, the number of domestic unified continuous publications, referred to as CN number for short. The front part of the domestic unified serial publication number consists of prefix CN and 6 digits.
Magazines are usually published on time according to the timetable written in the paper employment notice, and then the sample magazines are mailed to the authors. If the author feels that he doesn't really want to publish this publication, he doesn't have to pay the fee, and it won't have any impact.
I hope I can help you.
