The British children's edition is relatively light, just like the British pocket book. It will be better if you travel or watch it on the road. But it is not very collectible. Personally, since all versions are quite expensive and you have no special preference for the British children's edition, don't buy it.
Personally, I like the American version very much (there is only one version, and there are also hardcover and library versions, which are more luxurious), because the China version is the American version.
Detailed differences:
Differences between English and American versions of Harry Potter
In order to prevent piracy and protect her rights and interests, author Rowling only authorized five publishing houses in Britain, the United States, Canada, Australia and South Africa to publish its English version. However, due to transportation routes, costs and other reasons, the British and American versions are mainly introduced in China. In Britain, the version is subdivided into children's version and adult version, and the main difference between them is only the cover; In America, there is only one version. So, what's the difference between the American version and the English version? The editor of the American edition explained that it was mainly caused by the subtle differences between American English and British English. For example, Britain uses "jumper" to represent pullovers, while the United States thinks this means high jumpers, so the American version uses the word "swimmer", and the American version mainly makes such changes.
Take the upcoming Harry Potter 6 as an example. The cover and binding of the American version are different from those of the English version, but the content is the same except for some words, and even the page number is the same, all of which are 672 pages. However, according to the author's comparison of the past two versions, the paper in the English version is yellow, and the paper in the American version is slightly white. Therefore, there is a great contrast between the font and paper in the American version, and it is not easy to get tired when reading. In addition, the layout of the American version is also larger, and the spacing between font lines is also larger, which is also a factor that is easy to read. The author believes that the cover, binding and printing of the English version mainly reflect the classical mysterious style, while the design of the American version is more modern and clear. In the past few years, the number of American editions was very small, because the import cost of American editions was higher than that of British editions. Since Harry Potter 5 in 2003, China Book Import and Export (Group) Company, the largest book importer in China, has tried to increase the number of American editions, and the market response has been good. For this year's Harry Potter 6, the company will continue to increase the introduction of the American version, because the American version is slightly more expensive, but it is really good for protecting the eyesight of young readers.
In fact, there is another point, that is, the American version began to be shipped out of the United States on June 27th, which is 19 days longer than the global simultaneous release date, so that importers can make all kinds of preparations, while the British version can only be shipped on July 7th at the earliest, leaving importers only nine days to do all the operations such as booking, transportation and customs declaration, and the time is very tight. Because of the uncertainty in the import process, importing two versions at the same time is also a measure for importers to ensure the listing of books in July 16. From this point of view, the American version will arrive in China before the British version. Even if the domestic transportation time is excluded, small and medium-sized cities can definitely guarantee to receive the American version before July 16. Readers who book the American version in advance and need to mail it are also expected to receive the reservation earlier after July 16.
