Amazon doesn't publish sales figures or any other meaningful statistics.
Here is my attempt to crack the figures for today, March 5, 2018
Amazon offers their affiliate members a search tool for products. If you search for "book" in the entire Amazon range you'll get a figure. Same if you search for book in Kindle only. Likewise you can search the entire Amazon range for "hardcopy", "paperback", "softcover" etc. and produce more numbers.
I'm aware that this has been done before. I believe the Kindle numbers are reliable in most comparisons. However, the total number of books on Amazon seems to have been inflated in the past when different search engines were in place.
I came up with these 2018 numbers:
Total Kindle eBooks 6.9 Mio
Hardcover Books 4,6 Mio
Paperbacks 13.3 Mio
add softcover, audio and others you come up with a figure of around 23 -24 Mio books in total. This roughly corresponds to the search "book" on all of Amazon.
You might be interested that a similar search three years ago produced a total of 3,3 Mio Kindle eBooks. In other words, 1,2 Mio eBooks are added to Amazon every year. That's 3,288 a day or
one new Kindle eBook every 26 seconds!
