Me:  i see there have been several follow-ups, 
which i haven't had time to read yet.  But let me say
that i agree, and i have exactly this experience many times:

On the other hand these generalities are always interesting
and educational, so the time is not totally wasted!
In fact time spent in the library is never wasted.

The best solution is to add in brackets,
on the same %D line, something like [background] or [suggested by]
or [related material]
