Ironic? It was the publisher that broke LOTR up into three books; Tolkien presented it to Allen & Unwin as one book.

I’ll give you the benefit of the doubt on that one. I seem to recall that all three books where written several years apart and published as written.

But still, it’s ironic in any case since it proved to be a very good marketing technique.
