Snapshot: December 1 2009

I generally run this information through Jungle-Search (it’s just easier than Amazon), and there are some vagaries in the searches (both there and on Amazon).  I do try and run it the same way every time, so unless Amazon changes something, it should give you a pretty good idea.

I often see people who complain that the price of Kindle e-books are going up…in particular, that there are fewer books at $9.99 or lower.  I’m happy to report that the percentage of books from a penny to fifty dollars under ten dollars has stayed about the same: in fact, it went up again.  For recent titles (released in the previous month), it went up even more.  The number of newspapers jumped up, as did free non-public domain titles.  I’ve decided to start tracking Spanish language books: I’ve been telling people I expect to see more involvement with foreign publishers and in foreign languages.  Of course, I’m looking at just the US store…I’m not tracking how many are available outside the US.  Overall, things continue to look good.


  • Data was typically drawn using  There are a number of possible sources of errors (JS, Amazon, me), but these are probably pretty good
  • The free books referenced here are from the Kindle store: there are many other sources for free books
  • My search for textbooks definitely has false positives (books that aren’t really textbooks).  I search for -domain (to eliminate public domain titles, which would be older books, generall) textbook.  That would find a book about textbooks, for example
  • I searched for “Spanish edition” to find Spanish language books.  That has some false positives as well
  • I look at price percentages of books in the range of one penny to fifty dollars, to eliminate freebies and limit textbooks
  • This information is based on what a United States customer sees
