What folders contain this item?
One of the things I love about Zotero is how you can have the same item in multiple different folders simultaneously. (Often a paper applies to more than one conceptual topic, and I also maintain a "to read" folder of things I haven't gotten to yet. So it isn't rare for me to have the same paper in three or four different folders.)
What I'd like, though, is two things:
1) A way to click on an item and somehow see all of the folders in which that item is currently stored. (I'd like to know all the places I've filed it.)
2) A confirmation -- "do you really want to delete this?" -- when I try to delete an item from the *last* place it exists. (In other words, if an item exists in three folders, and I delete it from one of them, I should not get the confirmation. Neither should I when I delete the second. But when I try to delete it from the last place it occurs, and all my notes and attachments are therefore about to be erased, I would like the confirmation.)

@2: Even if you remove an item from all collections, it will still exist in your library.

2) isn't necessary because it doesn't have the function you think it has. The item continues to exists in the library. If you delete it from there you do indeed get a confirmation dialogue.
EDIT. pfff. 57secs....
This is made worse by the fact that the word "collection" does not imply anything particular about usage as, say, calling it a "playlist" would. Even though playlist would be incorrect from a media standpoint, it would be more accurate and informative from a usage standpoint. Not that I'm advocating calling collections playlists.
I do agree that the logo is a bit confusing. I don't think squares would do, because you do want people to intuitively drag things around onto collections, between collections etc. But this is worth thinking about.
OTOH, I think wheezepuppet's concern (#2) about deleting an item from the last collection in which it exists is due, in part, to the mistaken notion that items actually exist in collections as opposed to just being listed there. Nobody would ask that question about an iTunes playlist (sorry to put words in your mouth wheezepuppet, obviously I'm guessing here, and you should feel free to correct me).
As for white boxes, I should clarify--that wasn't a real suggestion, but an example to suggest that no usage clues are better than incorrect usage cues.
I don't feel that this is a minor issue in terms of this discussion. Not having hierarchical organisation would make collections far less usable for me - I currently have 50 collections going up to four levels deep.
I don't feel it is a fantastic idea but the best icon I can think of at the moment is the simple bullet point. As someone who uses outlining software and similar techniques when taking paper notes this image immediately suggests hierarchical organisation, collapsible lists and drag-ability, all of which are important features of collections. The main feature that is not suggested by bullet points is that of collections as containers for items, however I would have thought that that would be reasonably obvious as otherwise collections are devoid of useful purpose.
