Amazon.com Books For Kindle Count

Today I decided to take a break from Kindle 3 Reviews and do something I didn’t do for a long time – crunch some dry Amazon Kindle Store numbers.

I’ve been tracking number of amazon.com books and blogs for Kindle since March 2009. Previously I published these numbers on a monthly basis. With Kindle 3 released and getting great reviews it’s time I did so again.

There were 242,488 Kindle books when I started keeping track back in March 2009. Since then this number almost tripled to become 685,380. By looking at the graph you can see that apart from bump here and there the number of Kindle books still grows in a linear fashion. Largest spike to date (roughly 70K books) was in May 2010.

As you can see the majority of growth happened in non-fiction and history genres. Now lets dig deeper into smaller categories.

If you look at this graph carefully you will see that back in 2009 “Comics & Graphic Novels” and “Cooking, Food & Wine” categories didn’t exist at all. They first appeared in October 2009 and May 2009 respectively.

Number of blogs more than doubled since I started keeping track and just crossed 10,000 mark several days ago. Although you can only subscribe to blogs that published themselves on Amazon Marketplace, you can still read the rest in the browser. Although this is not as convenient.

As you can see, most of the growth can be attributed to “Lifestyle & Culture” category.

So effectively the amount of content available for Kindle more than doubled over last 18 months. Impressive, isn’t it? But if we look past raw numbers, the picture can definitely be better. eBook industry right now is where digital music industry was years ago. Publishers are still wary of the new technology and sometimes don’t want to deal with it. While Amazon as a store works hard to get the most bang for the buck by signing on books from bestseller lists (and I have to admit they do a good job at it too) many great by not so currently popular books stay overboard.

Try searching for Robert Heinlein books on Kindle for example. You’ll find only six. But don’t rush to trade your Kindle in for Nook, Sony eReader or even iPad – you will find exactly the same selection there – I’ve checked. However if you head over to pretty much any torrent tracker you will find full Heinlein bibliography floating around in zipped PDF files. So while publishers cling to their old business models or argue who is going to charge whom and how much, books are being pirated because there is absolutely no way to get these and other works of literature in digital form. Hopefully it will get better just as it did with music industry.

I’ll wrap up with the usual daily Kindle 3 checkup. There are 264 (up 44 from yesterday) Kindle 3 reviews so far on amazon.com with the following breakdown: 179 – 5 positive star, 42 – 4 star, 10 – 3 star, 10 – 2 star, 23 – 1 negative star. Kindle 3 is still backordered until September 17th.

October 2009 Summary

If you recall, there was a massive drop in book numbers in the last day of September. Well during the first week of October these books came back. So if we disregard this anomaly and consider 357,724 to be the final count for September, then with the final count for October being 368,373 we get an average of 343 books per day added. Otherwise if we take 372,556 to be the initial count then average increase would be 835.

The number of Kindle blogs increased from 7,179 to 7,355 (+176) giving us 5.7 new blogs per day on average. Notice weekly sharp drops. It looks like Amazon is either reviewing blogs on a weekly basis or they are just pruning out stale/dead blogs periodically. If you know of a blog that was on Kindle and no longer is – please let me know. This blog is still there – alive and well.

As for events, there were several major Kindle related themes in October 2009:

I’ve been quite busy with different things during the month of November so I didn’t blog as much. I know it’s almost time to be writing November summary, but better late than never.

September 2009 Summary

There were some oddities with Kindle content count in the month of September. Just look at these graphs below…

Kindle book count was steadily increasing at 280 books per day for the entire month and Kindle store was about to post a gain of 8K+ books for the month when on the last day there was a sudden drop of 15,245 books. So final monthly delta ended up being -7,131 books with average loss of 238 books per day. I’ve checked today and the numbers are still way down, so it wasn’t a one day thing. So the final count is 342,479. This is about as many books as there were in the beginning of August.

Similar sharp drop happened in Kindle Blogs on the 5th of September. 222 blogs were eliminated from the marketplace. If we disregard this drop, number of blogs was increasing at around 10 new blogs per day which is still fewer than August gains. However with this drop factored the number of blogs increased by only 8. By the way, BlogKindle is still there on the marketplace and you can subscribe to it using your Kindle.

Perhaps Amazon decided to do some house cleaning and eliminate low quality and duplicate content. Perhaps they have made the admission rules more strict. This seems to contrast with Sony/Google strategy of piling in as much public domain content (which is mainly low quality or outdated) to impress customers with raw book numbers.

And finally, here’s a recoup of what happened in the month of September:

August 2009 Summary

It’s time to publish previous month stats and summaries again.

Kindle book count had several ups and downs during the month of August, finally settling at 349,610 (just 390 books shy of 350K) for an overall increase of 13,713 that translates to 442 books per day on average. This is 3 times lower than previous month gain, in fact this is the slowest growth I’ve observed since I’ve started counting Kindle books this year. I hope Amazon will pick up it’s pace or my book count predictions might be off. If I were to speculate, I would guess that Amazon is periodically prunning self-published books to avoid incidents similar to the one with Orwell books.

Kindle blogs, on the other hand, saw a healthy increase of 807 (almost twice as many as in July) ending at 7,171. This is 26 new blogs per day on average. Although if you look at the chart you can see that majority of the blogs were added on the 12th. If I were to speculate again I would guess that Amazon was holding off on approving blogs until they’ve internally decided on some kind of policy. Either that ot they’ve struck some kind of wholesale deal with some blog mogul.

And now a brief recoup of August 2009 Kindle news:

July 2009 Summary

It took me a bit longer than usual to come up with the summary but here goes…

Kindle book count increased 41,016 (13.8%) in the month of July with final count being 335,897. Notice odd fluctuations between the 9th and 14th. Perhaps some publisher couldn’t make up their mind… Besides that book growth was linear at about 1,300 books per day.

As for Kindle blogs, there were 445 (7.5%) new blogs in July with final count being 6,364. It looks like bloggers are loosing interest in Amazon Kindle as publishing blog platform. The growth was linear with a rate of 14 new blogs per day. As for BlogKindle.com, it more than doubled its number of Kindle subscribers.

Since there were no major changes in subject disstibution compared to June 2009, I’m going to skip these charts this month.

Here’s a scoop of what happened in July 2009:

June 2009 Summary

There were 294,881 books at the end of May 2009 and 312,591 books at the end of June 2009. So 17,710 books were added to Kindle Book Store during June. This is slightly more than 6%. On average 590 books were added per day. This is less than average of 641 books per day during the month of May.
