<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">records office</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this before)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for registry that I've seen before include "Office where records are kept" , "Official written record of names, events etc" , "Place to keep records" , "Place of record" , "where files may be observed" .)
