It stands to reason that reserachers want to keep info where it is still easily visible, as money may not be available to do on the ground footwork, and printed material is also then removed. Look at the Mercer Island yearbooks - none can be found. Probably before people were asking difficult questions the yearbooks might have been able to be located.

Look at the Mercer Island yearbooks - none can be found.
I would stipulate that none can be found from a source freely available to the public.
I simply can't believe that every single yearbook was collected and/or destroyed. How many students went to that school? Every book purchased for that year by every 9th-12th grade student just magically disappeared? Even every yearbook for each of the years she went to Mercer suddenly disappears? I just don't buy it. The key is "freely available to the public".

And the same thing applies with the publisher. I can still go and get a copy printed of my yearbook despite having graduated over 30 years ago.
Did the yearbook publisher destroy all of their originals? Or do they expect to get paid for a copy or get paid not print any copies?
