Amazon used to sell a Kindle version of A Manual of Style for Contract Drafting, but it doesn’t anymore. (Something to do with Kindle versions being vulnerable to piracy.)
But you can still get MSCD on Kindle, by buying the ebook version sold by the ABA here. It’s a MOBI file, so you can transfer it to your Kindle using the steps described here.
If you encounter any difficulties, let me know.
