I just came to the realization that lists of books you reference

are pretty meaningless.

A better taxonomy:

• A keep forever book; you'll be happy to pass it on

• Books you must read in their entirety, but probably just read once

• Just read these pages/chapters

• I read the book so you don't have to, so there's the tl;dr

• A waste of time, I just added it here for the sake of completion

Any others?

I'm making a list of design books, but categorizing them in similar categories above.
