TRVTH.  I used to do exactly this when HP sent updates.  I put replaced
pages at the back of the manual, and usually did not refer to them thereafter.
When the binder filled up, that’s when I might consider discarding them.

HP had the habit of printing the update date and sometimes update number near
the bottom of the updated pages.

Sometimes I have come across shrink-wrapped manuals and later updates, and
scanned them as found.  I wouldn’t want to deny other people the opportunity
to apply updates to manuals, you know?
