While editing, I've come across titles that don't fit into any of the listed types because they are European in origin. For example, Y Square or Yonen Buzz.
Currently, they are listed under OEL, I suppose because it portrays them as Western in origin despite their original language being German or another language. I think it would be useful to have a new type differentiating European works. I am not quite sure what one would label them. Euro? OEW (Original European Work)?
