Non-free (as in beer) Kindle public domain books.
The amazon Kindle store has many public domain books that are free-as-in-beer ($0.0) such as Treasure Island.  Why are some public domain works not free-as-in-beer (about $1 or $2) such as Shakespeare and HP Lovecraft compilations?

Is it because these volumes are compilations and you're paying for the editing?

Not that there's anything wrong with this,  It is legal (US and Australian Law) to sell public domain works for a fee, just as it is to sell open source software.  I'm just wondering what I'm paying for.

Thanks.
