That all depends on how things are done. If you post on the landing page that "You have three means of transportation, A Ferrari, a three-speed bicycle, and a bass boat; click to see how each is used and why. And when you read about the bicycle you have to hit the back button to link to the car, etc. Then I'd say that was not good, but if you could go to the Ferrari page from the bicycle page then good.
If you made a 27 chapter book and each chapter flowed to the next - good. But if you stopped reading in chapter 18 and when you returned to the site you had to go through all 17+ chapters to get to where you left off - bad.
And about the vehicles - if you only had a couple of sentences to say about each, it would be better to have everything on one page.
What is your large file about and how are you thinking of splitting it?
