I've had the same problem, not remembering what a book was about etc. The easiest way I've found is to make a list of book blurbs or descriptions, I make a different one for each group. Then I use a very small simple app that sits in the doc (I use a iMac) I don't know if theres a Windows version =( It's called "Kindle Blast" You just copy what you want click Kindle Blast type in a name and it's sent right to your kindle (Needs to be plugged in BTW)
Here's the only place I've found to download it.

Developers description:
Kindle Blast is a free and easy to use Automator workflow for easily putting text onto a Kindle.
Kindle Blast will provide you with a quick and easy way to get text from your Mac to your Kindle.
How To Use (make sure your Kindle is connected to your computer and the disk is mounted):
· When you are somewhere where there is text that you want to read on your Kindle (for example, a long web article), highlight the entire body of the text and copy it to the clipboard (as in, regular Command-C)
· Click on Kindle Blast in your Dock
· You will be asked for a title. Type in a meaningful title - the file name will be based on this, and the Kindle will use it nicely as the document title - so format and capitalize it in the most human-readable way
· Press "OK" and Kindle Blast does the rest
