As you probably have been reading on here I have self published my crock pot recipes on Amazon Kindle. I did that because so many people now read on devices like Kindle, iPad, other tablets and even on their iPhone. I think Kindle recipe books are the way of the future as you can now look up a recipe and have it in front of you as you cook. That's great I think!
I have a Kindle eReader myself and enjoy reading on it especially when I travel. Before that though I was reading books and recipes on Kindle for PC so I didn't miss out on the free and very low price books you can find on the Amazon site. Most books are priced from 99c to $3.99 so you can find recipes for anything you want to make.
What I like about using kindle books when I cook is that I can make notes on the recipe I am making, bookmark a recipe or highlight text. You ruin a real book if you do some of those things. It can also come with me wherever I am cooking.
I can also search for a recipe that has a particular ingredient eg onion and it will list where onion is mentioned in any of the recipes in a particular cookbook and you can go right to those recipes. I think that in itself is great and saves me time.
Here's a quirky little video I did of my Slow Cooker Soups book I have published on Amazon Kindle. Its short but fun.
