Works published in multiple editions/formats may have the records for 
those formats collapsed into a single UW WorldCat record.  For example, 
in a search for ‘Twelve Angry Men’,
 the first item in your results is a DVD edition (MGM Home 
Entertainment, published 2001), with copies in Bothell and Tacoma. 
 Clicking the “Editions and Formats” link from the results list reveals 
we own two additional DVD editions, as well as a Bluray and a sad little
 VHS edition, all held at the Seattle Campus Media Center.
In
 your “editions and formats” results list, the default sort is 
date/edition.  If you’re looking for what’s available at UW Libraries, 
change the sort order to “library”, which will pull the UW results to 
the top of your list.
In
 UW WorldCat, checking for additional formats and editions is important 
for titles where there are likely to be multiple formats or productions –
 chiefly media, books and movies that have the same title, and “classic”
 literature in which there would be many editions.  Also note that if 
there is a specific characteristic you are limiting by (perhaps looking 
for that that sad little VHS tape), you can use that term in the search 
or facet and the resulting record will be the one for that specific 
edition.
