two duplicate books but different filename

I'm guessing these scenarios are not so uncommon with public domain works from different publishers. Just today I had to hide away two copies of Calvin's Institutes, and I still have a third copy left in my library (and all three of them translated by Henry Beveridge!). I wanted to hide the last one as well but it's from the Great Books series and I'm too OCDish to break up the collection.

I agree the collection must stand!  [:D]

Not only essentially the same. They're identical down to the page numbering.

The only difference is the price. [^o)]

Crime and Punishment | Logos Bible Software $7.49

Harvard Classics Shelf of Fiction vol. 18: Crime and Punishment | Logos Bible Software $10.79

I'm too OCDish

Don't feel bad; I have relatives and friends who suffer from ODD (Obsessive Diagnosing Disorder).
