Another user is working on adding reviews to a long list of articles, and sometimes adds the coves as he goes; I'm sure he won't mind if someone else beats him to it.

A different user who is no longer on Wikipedia was helping me out with covers previously and was able to add the majority of what I asked him to look at, but he could not find a small percentage of them. These may be a challenge, but feel free to see what you can do.
