Create New Heading in Sidebar

I’m using the standard interface (Kubrick) on WP 2.2. I want to create a new category in my sidebar — call it “Good Reading Online”.

It will be like the Blogroll in one respect: It’s a list of links to my favorite online e-books. Can anybody tell me how to create a thing like that?

I’ve already tried the theme editor. I thought I could simply copy the code for the “Blogroll” and paste it into the code a second time, then give it a new name (e.g.: “Good Reading”), save it, and run. Too bad I can’t do that. I can’t even find “sidebar” or “blogroll” in the code.

I’m stumped. Again: can somebody give me some help here?

Thanks for your patience. I am only an egg.
