I was making a collection of The Harvard Shelf of Fiction and noted two Crime and Punishment books,

and

LLS:HCSF18

HCSF18.logos4

they have the same 1917 copyright

I have attached the infor pages here. not a huge deal, just curious as they are essentially the same books.

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.
