Pressing escape while in a blueprint should bring you up one layer.

When in a blueprint book, pressing escape currently closes the gui completely. I propose that it should only close the book/layer you are currently in, to make navigation easier.

I'm all for the default shortcuts I'm using everywhere working also ingame.

I like there being a shortcut to go up a level. Personally, I would prefer "U" (if not already taken), as it's the shortcut to go up a level in Gmail and many email programs.

Alternatively, ESC could exit out of the library screen completely, or perhaps have some other function (such as immediately going back to the root / main library screen).

The specific button doesn't really matter I guess. it could be its own modifiable shortcut.
