I'm modifying the build a blog tutorial to make myself a reviews database. My plan was to display my data like this:

- Author
- Book 1
- Book 2
- Author 2
- Book 1
- Book 2
- Book 3

But then I realized that even if I have two books with the same author, I could only get:

- Author
- Book 1
- Author
- Book 2
- Author 2
- Book 1
- Author 2
- Book 2

I was thinking about it, and I was wondering if I could make the "Author" kind of like a category - except that I already have categories like "fantasy" and "romance." Would it be possible to put reviews in both the "Author" and "Fantasy" categories? Or can I only have them in one category at a time? Or could I get the same effect using a "tag" system? And how would I go about doing that?

Never mind, I figured it all out.

How did you do it? It might help others if you could post your solution.

It was easier than I thought it would be - I just followed the Categories tutorial again from the Build a Blog series to make an "authors" category. I made a couple of tweaks to modify how it displays my information, and it works alongside my genres categories perfectly.
