I used to own a single volume trade paperback Lord of the Rings edition that had appendices at the end which were useful for keeping timelines straight and providing enjoyable additional material.
I'm considering purchasing a three-volume hardback edition illustrated by Alan Lee to replace my long lost copy but I'm concerned about whether the appendices are included and--if so--how they are split between volumes. If this varies between different three-volume editions, where can I find details for popular editions?
