Make those Links Stand Out

So in this experimental CSS layout that I use, the links were completely invisible in my postings, which I think is a very bad thing. Say if I was trying to point a reader to a book that I want them to read, if it does not stand out on the page, how do they know I want them to click on something? A good example would be This book here as a link, if I didn’t have my links set up on my CSS as a different colour from my regular stuff, how would you know to click there?

I have taken a bunch of books out about how to fiddle with the Style Sheets for web sites, so expect more commentary on this type of stuff.
