Thanks for the replies. I've already tried these, and unfortunately they won't help in my case.
Basically, I was trying to find a way to make the 5 'A Hunger for Knowledge' books in West Bjora Marches more visible as they are extremely small and incredibly easy to miss while trying to hunt them down. I've found 4, but of course the last one is always the hardest to get (and I know I could just wiki it, but what's the fun in that?)
Although I do wish the achievement at least gave some type of hint where each book is located!
