I believe the answer is:
out
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">published</span>' is the definition.<br/ ><span class="explanation-format__explanation">(a published book is 'out')</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for out that I've seen before include "No longer imprisoned" , "Old hat" , "jury considering verdict" , "Escaped" , "A way to escape" .)
