In my opinion, it is essential for an indie author to own a Kindle. Even if someone else formats your ebooks, go out and buy a Kindle. Nobody's perfect, and that includes your formatter, no matter how good he or she may be. It's called human error, and it's a fact of life. Everybody's bound to miss that little something.
Plus, you're trying to sell ebooks, so you should own an e-reader. And you're a writer, and every writer starts out as a reader. So what's not to love about a Kindle, which you can fill with books you
enjoy, pick up whenever the mood strikes you, and get lost in another
world for a while?
My Kindle is essential in checking my own ebooks. After creating the mobi file I thought my last publication, Larvae, was good to go. Then I uploaded it to my Kindle before uploading it to Kindle Direct Publishing. While reading it over one last time I found a repeat of "has" and two typos that I missed when reviewing it in any other format. Just goes to show: look over your writing every which way possible. Check it on your computer, print it up and mark it with that little red pen, and then triple-check it on your e-reader before you click that button to publish.
I've downloaded many an ebook that has huge gaps between paragraphs, no indent at the beginning of paragraphs, missing line-breaks, all sorts of formatting goofs (mind you, it's not just indie books with this kind of stuff). I'm forgiving, and will give a book a read even if it does have errors, but these sorts of things annoy the heck out of some people, and I'll bet that many of these stop reading at the first sign of wonky formatting and never pick up the book again (that or delete the sample of your book they downloaded and never purchase anything you publish ever again). If you want your book to stand out among the thousands upon thousands of
indie books out there, you must make it as professional as possible.
This means with few to zero typos, and without formatting errors. Owning a Kindle will help you cut down on these gaffs.
If you don't want to spring the funds for a Kindle, at least download the Kindle reading app onto your Smartphone, tablet, or computer. To check your epub files, try out Adobe Digital Editions. Both are free.
And don't be dismayed if you find errors in your work, even after you've published. One of the great things about ebooks is they are easily altered. Dynamic. Love that word. Take the book down for a day, make your adjustments, and put it back up for sale. No harm, no foul. But you might want to let your readers know there's a new, improved version of the book out. Just my thirteen cents. Until next time . . . peace.
