dwig, I told you I am a newbie....
Step 1 wasn't a problem.
I assume step 2 was to click on the Authors column. Right? I couldn't find an Authors "section"?
I found an incorrect entry and right clicked on it. I wasn't given a "rename" option. But I renamed the author to the correct name and it just renamed the author on that ONE book only.
Newbie alert!!!!
