My guess is the books required only remain static for certain classes.

Like Transfiguration, Potions [and double potions probably requires 
another book], and Herbology all require some standard texts.

But Lockhart, when teaching, required all his books for his DADA 
classes.

We're not sure what Lupin required or Faux Moody, are we?

Then there's the fact that the books may carry updates the previous 
year's versions do not have.

The only way it'd be viable to hand the books down over time would 
be, I'm guessing:

is if there's a magical Master Edition in some publishing house 
somewhere, that automatically updates all editions of it that have 
been sold and are still in legible condition.
