Is it time to rethink the private/public distinctions for museums? | Sauropod Vertebra Picture of the Week

"Just as we were mistaken in focussing primarily on the for-profit/non-profit distinction between publishers when what we really cared about was the open/non-open distinction, could it be that we’ve been misfocussing on the public/private ownership distinction when what we really care about is availability of specimens?

Is there a way to be confident about which museums will and will not always make specifimens available for study?"
