Indeed.
I should have added a disclaimer I found that number on a forum. I was trying to find a better source, but didn't manage. I just knew this novels were massive.
EDIT:
According to the same forum where I got the numbers... each 'volume' was separated in several books... kinda like Haruhi's more recent novel was published in 2 books. 4th volume just came out this month in 3 parts.
Volume One has 2 books
Volume Two has 2 books
Volume Three has 3 books
