1. Some authors' manuscripts/works/books cannot be published in China for many reasons, such as the long domestic publishing process, complicated review process, high cost and long time. Whether they are published or not depends largely on the preferences of publishing house editors and the social situation at that time. So some excellent works can't be published in China, but they may be very popular abroad. 2. When contacting foreign publishing houses, should I use Chinese or English? In fact, it still depends on the manuscript itself. If your manuscript is written in English and you are fluent in English, it is no problem to contact the publishing house in English. When your manuscript is written in Chinese, you can try foreign publishing houses with Chinese editors, such as the International Institute of Science and Technology &; Education, submission email address contact@iiste.org), while some publishers, such as Institute of Electrical and Electronics Engineers (www.ieee.org), explicitly do not accept Chinese manuscripts. Be sure to pay attention when contacting. Don't let your manuscript sink to the bottom of the sea. 3. Pay attention to the release method when releasing. Famous authors (such as Han Han and Jing M. Guo) can talk to the publishing house about conditions, such as getting a share under the specified printing volume, and publishing books is easy to make money; There is also a class of college teachers who can write their own books as teaching materials and sell them every year. Authors with less influence should consider the actual situation. At this time, there may be two ways to publish a book. One is to buy an independent ISBN from a relatively small publishing house in China at a high price, and the cost is about 8000 ~10.5 million, and then print hundreds of copies (that is, self-funded publishing, which is popular in China); The other is to contact foreign publishing houses and print on demand to share a piece of the cake according to the number of books sold; This road is faster. Generally, an efficient publishing house can arrange publishing in 1 month to several months. 4. Benefits of printing on demand when publishing a book: The success or failure of this method depends on the quality of the book (whether there are potential readers) and the reputation of the publishing house (whether it can be well publicized). For example, if a book is priced at $230, according to the cooperation agreement, the author will get a profit of 10% to 65% for every book sold, and if he can sell hundreds of books, he can get a relatively generous return. For example, PenPress gives the author a 35% share, while IISTE can give the author more than 50% share. Several well-known book publishers: 1. Griffith Press, USA; Contact information: hodi@mindspring.com (English only) 2. The International Association for Science, Technology and Education Research from the United States gives authors a higher share and responds faster when consulting; Www.iiste.org, the Chinese editor, doesn't speak fluently. His email address is: 3. Penpress, a publishing house in contact@iiste.org, England, has been in business for a long time and can give the author 35% of the share. Contact: info@penpress.co.uk (Chinese is not supported, English is recommended) 4. IEEE:j.germano@ieee.org (I don't know Chinese, my reply is slow, and I don't seem to like authors whose mother tongue is not English).
