Don't forget to order your supplies for this year's International BookCrossing Day (April 21)! The last day to order them is March 25, because we'll need time to get them to you before the big day arrives. And this year's labels were designed by Azuki and they're great. So don't miss out, get your orders in while you can!
The target attribute specifies where to open the linked document.
I know. That's why this use doesn't seem to make sense to me. Maybe it's useful if you have a ton of such links and they'll all open into the same window as the first? In any case, it can safely be left out. Links open fine without a target attribute.
