This is related to the suggestion "All metadata and content displayed for a work should use the same instance ISBN", but more specifically I'm seeing a problem with movies with different release years, but the same title (and same DVD publisher).

I can see this making sense for certain things - for example a book like The Grapes of Wrath, which we have several different editions of. The text is basically the same - there may be different forewords or other supplementary material, but for the most part it's less likely that a patron will be choosy about which edition they want when placing a hold.

However, I came across this listing which combines the 1934 and the 1990 adaptations of Treasure Island. The 1934 film is listed as a 2006 publication date, and the 1990 adaptation has a 2011 publication date. These are obviously two very different films, but it would be difficult to place a hold on one specific version or tell which is which. The image and description seem to be for the 1990 version.

If you click on the details "i" icon, you can see some credits (not actors or director, but some more esoteric ones), that if you did some sleuthing you could figure out which version of the film they belonged to, but it is not helpful in practical terms. I was only able to distinguish them since I have direct access to Polaris.

(Strangely, there is a link to the 1934 version in the "You May Also Like" section, but it just links back to the same listing.)

These have two separate bib records in Polaris.

Another example:

This entry for A Star is Born seems to encompass the 1954 (showing 2010 publication date) and 1976 (showing 2006 publication date) versions.

Similarly, the listing shows artwork and description for the most newly published item which in this case is the 1954 version. There's also a link to the 1976 version that is a link to the same listing.

Other titles, like "Alice in Wonderland", do not seem to have this problem. I think it's probably because the publishers have different names.
