I think I am going to plant the sweet potatoes. The sprouts off the top of the potatoes haven't gotten any bigger in weeks, despite plenty of sun and the jar staying full of water. It just sits on the deck mocking me. It's going in the potato place today.

Edit - I did it. I pulled what I was absolutely sure was clover. I still have other stuff that may be potatoes or just weeds. I guess I'll find out in the fall. There is really good soil over there, a couple of years worth of compost, the dirt is black. Hopefully I get something.

Wow really? My sweet potato now plants are over a foot almost 2 foot long on some of them. Even the slips still in cups have doubled in size. Did they root at all?

I've never had any problem checking files this way after publication, not have I had my books taken off sale if I checked files this way. This seems like the most direct way to check your files. I'm wondering why you're afraid to. Did something happen to you this way once?

On the subject of Independence Day, Kobo's running a sale this weekend.  Some of my stuff's in it.

Trilogy box set is on sale

Thanks, guys. I did both. Got my spouse to enroll in a free-two month KU subscription and download the ten books that are in KU. Then I tried the "Edit Content" trick on the others and got exactly the information I needed about which file version was on Amazon.

What I will do with it is a different story. I do not format my own books, and in the past I've had my formatter update them. As I got busy and the formatter did, too, not all of them got updated before that formatter turned me loose. Starting over with a new formatter who says any changes in a book he did not format would require a complete reformat, I don't know if I'm walking into the a spiderweb for the future. Plus the idea of paying all over again for formatting is daunting. I don't know enough about formatting to understand why a file would have to be reformatted from scratch. I've been considering sending one of my books as a revised Word doc to D2D instead for their free formatting, although I'm not sure how much prep work I would have to do in advance, such as not indenting the first paragraph in a chapter, and the like.   

I'm not sure of the value of all the updates I've done in the past, either. At first it was just dealing with a few typos. Then it was updating my Books By pages with links in the frontmatter and backmatter to encourage instant purchases. Then I changed covers and needed to remove the old cover design credit from my copyright pages and have the old embedded cover removed. Then I added some first chapter excerpts at the ends of some of the books. Then I finally got it together to produce a free novella as a newsletter signup incentive, and I had that, with the cover of the novella, added to the frontmatter, and I also updated my link to Mailerlite from MailChimp in both front and back. A lot of fiddling, but my old formatter would do it for peanuts.

That's a lot of activity. I felt my edits to text were important, but I don't have evidence that all these pleas to sign up and to write a review and to buy the other books I have out have produced much of anything.

I could go into Bookshelf>Edit Details and see the file name, but as you know, that will cause Amazon to want to re-approve it. Even though I'd like to believe that Amazon will not take the book off sale while it is deciding all over again to approve publication, I don't want to take the chance this weekend.

Is there another way? I went to Content & Devices>Read Now and what came up on my Kindle for the computer was my original text, even though it has the correct, newer cover.

Is this another instance of Amazon never updating the file it sends to new purchasers? Others have said here previously that it won't bother unless there are substantial changes. But if that is so, how does anyone ever update a file to eliminate typos? Which is what I did a couple of years ago, but now I'm wondering if Amazon ever bothered to acknowledge the update and what can be done about it.

If you add a timestamp to your file you can just click "Edit Content" and view it to determine whether they have the right one. They show you the file name. No prompt to save and no changes register that would require a review.

But as others have said, if you already downloaded/purchased the book prior to the changes, they don't automatically push the new edition out to you (or any other reader who bought prior). You could try from another account, or you could check the "Look Inside" from the book's sales page.
