When I tried to duplicate the search, the record you cite shows no
libraries holding:
http://firstsearch.oclc.org/WebZ/MoreLikeThis?searchtype=morelikethese:sessionid=fsapp11-45633-f98nf6lm-jab2mk:entitypagenum=59:0
Not sure what you mean by seeing one library holdiong the Darton &
Harvey edition.
As for the larger issue, I believe that not all institutions open
their holdings to worldcat search despite having contributed catalog
records which explains the "no library holding" situation. That
and, unfortunately, deaccessioning.

Subject: [EXLIBRIS-L] OCLC (World Cat)
OCLC (WorldCat) will occasionally list an item as having one location
but the detailed entry does not list any copy, as for instance
http://firstsearch.oclc.org/WebZ/FSFETCH?fetchtype=fullrecord:sessionid=fsapp11-45633-f98nf6lm-jab2mk:entitypagenum=11:0:recno=22:resultset=4:format=FI:next=html/record.html:bad=error/badfetch.html:entitytoprecno=22:entitycurrecno=22:numrecs=1
Any explanation ? Thanks, Norman
