For an author who publishes a book at his own expense, he hopes to be as cheap as possible in terms of publishing costs, and generally we can start from the three aspects of book number type, publisher level and publisher preferential policies
First of all, regarding the book number type, different book number types are charged with different book number fees.
1) As far as mainland books are concerned, the e-book number fee is relatively cheap, and authors can match the publishers who can apply for e-book numbers in combination with the direction of the book.
2) As far as Chinese books are concerned, the Hong Kong ISBN fee is relatively cheap, which is cheaper than the e-book number, but if you want to find a Hong Kong publishing house to publish the book, there are restrictions on the evaluation of professional titles and distribution in the mainland, which is not suitable for most authors.
3) As far as international publishing is concerned, the ISBN fee is cheaper than that of a single ISBN, and if the institution recognizes international publishing, the ISBN is a very good choice, and it can match the book published by an international publishing house.
Secondly, it is the level of publishing houses, according to the level of common provincial, national, central and 100 best publishing houses, university presses, etc., relatively speaking, the provincial publishing house book number fee is cheaper, but not absolute. In addition, many authors who publish books with professional titles require at least national publishing houses, even if the provincial publishing houses have cheap book number fees, they cannot choose. Of course, if you can choose, you can give priority to the provincial publishing house.
Finally, with regard to the preferential policies of the publishing house, the publishing house has a certain autonomy to set the price for the book number, and they will launch preferential policies for the book number according to the actual situation of the operation, resulting in the book number fee being relatively cheaper within the given time, but this needs to be paid attention to from time to time and the publication plan should be determined in time.
