Comment 11 for bug 1315552

Confirmed on a 2.9 system. It seems there are more conditions to the duplicates than originally described and it's not specific to floating collections. Anytime you have a mismatch between Owning and Circulating Library, there's potential for this display issue to show up. Here is what I did to recreate it on a 2.9. system:

1. Title is Dune Road by Jane Green. I'm searching at the System level (Lexington System). It has 3 copies and all 3 copies had an Owning and Circulating Library of Lexington Main. All is well with the "show more details" OPAC view.

2. I went to Holdings Maintenance and updated one of the 3 copies to have a Circulating Library of Oxford, keeping the Owning Library of Lexington Main. Oxford is also part of the Lexington system.

3. When I go back to my search, again at the System level, I see duplicates. It's now showing 6 copies in the detailed view although the copy summary is still correct showing "3 out of 3 copies are available in the Lexington System."

4. If I scope down to the Lexington Main branch, it looks good. I only see the 2 copies with a Circulating Library of Lexington Main.

5. If I scope down to the Oxford branch, it looks good. I only see the 1 copy with the Circulating Library of Oxford.

So, scoping makes a difference here. Also verifying that this is only with the "show more details" display. The copy summaries are fine.

I also found that if I have a bunch of copies, the issue only shows up if I have a mismatch with one of the copies that shows on the "show more details" screen. For instance, if there are 30 copies and the first 10 show up in the detailed view, I actually have to make one of those 10 copies a mismatch before I'll see the duplicates. If I happen to update a copy that wasn't showing in the initial list, I won't see the duplicates. This is why it appears larger library systems with more copies might not bump into this as much as smaller systems where all of their copies show up on that initial search results screen.

I would say the easiest work around until the bug can be resolved is to turn off the "show more details" display in the OPAC. Not an ideal solution but the only thing I have to offer until someone can resolve the display issue. Hope this helps.
