The company announced the new limitations in a post on its Kindle Direct Publishing (KDP) forum on Monday. "While we have not seen a spike in our publishing numbers, in order to help protect against abuse, we are lowering the volume limits we have in place on new title creations," read the statement.

KDP allows authors to self-publish their books and list them for sale on Amazon's site.

Amazon told the Guardian that the limit is set at three titles, though this number may be adjusted "if needed."

The company confirmed that there had already been a limit to the number of books authors could list a day, but declined to say what this previous limit was.

The post stated that Amazon is "actively monitoring the rapid evolution of generative AI and the impact it is having on reading, writing, and publishing" and that "very few" publishers will be affected by the change. Authors and publishers will also have the option to seek an exception to the rule.

According the the Guiness Book of Records the most published works by one author is 1,084 by Scientologist founder L. Ron Hubbard (USA) whose first work was published in February 1934 and the last in March 2006. So the three a day suggested by Amazon is out of the league of most humans.
