<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">paper quantities</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for reams that I've seen before include "a very large amount" , "Scrapes the barrel" , "Lots of paper" , "Large quantities (of paper?)" , "This much paperwork" .)
