|kindle with spooky disembodied hand|
This will be some links, really, cuz I'm no techie. But what I did was read some stuff and found clear explanations how to convert files to read on Kindle. I also have done it with my friend's kindle and it worked a charm.
Some small presses aren't getting all their works on Kindle, and it's nice to read your stuff where you want, DRM notwithstanding. (Grr DRM). For the record I lean a lot more to the "free and fair use" side of the argument. It's my opinion that several chapters, or even the whole book available on a website for free actually SELLS BOOKS. Google Cory Doctorow for reasonable, informed opinions and to learn his experiences.
The first link is THIS, cuz I felt it was the most technical, comprehensive explanation with links to code to do it, and it has basic info on the device as well. It's long, but worth the read. I think "hack" is a bit provocative, and often unnecessary.
Amazon lets you email all sorts of things to your kindle email account to download to your Kindle. Clear instructions on how to do that can be found HERE, right on Amazon.com.
I've done it and I'm clearly an idiot, so it must be uber-easy!
I'm happy to add other links as they're suggested, but what I found further on in the Googles were basically repeats of this same information. But definitely tell me if you know better, clearer instructions.
