LibraryThing - Week 9 Thing #19

I started off very excited about this site. Finally, I would be able to get a little bit of a handle of what books I have at my home. After I had entered about 20 books, I clicked over to take a look at my list. I had inadvertantly tagged all the books with the title of the first book I entered. I have been clicking thru the site for about an hour and cannot figure out how to undo these tags. I am sure it is something very easy...I just can't figure it out!
