I am glad newer games gave an exhibits option to make things easier. AC:NH does this best by marking donated critters in your Crittipedia as "donated".
This is easily the most annoying thing about GC
The way Blathers' dialogue slows down when you try to donate something already in the museum is just a kick in the shins
