Hi Mark,
you are right. I'm missing this feature too. While it's possible to export documents from group libraries to zotero-rdf Format (with notes, attachments...) and to re-import this entries into MyLibrary without problems. It is not possible to do it the other direction: exporting from MyLibrary in zotero-rdf Format an re-importing it in a selected group library. This feature should be added.

While drag & drop between group and mylibrary acutally do not work completely (notes, attachments are missing) this could also be a workaround to exchange documentes with notes and attachments between mylibrary and different group libraries.

Where does it say that? Dragging collections into group libraries isn't currently supported.

Ahah, but only items, not collections

dawning

My assumption was collections because they are more likely to exist prior to the group being set up.

would love to see that feature as well

Just adding that it would be very nice to import into a group library -- I just highlighted my Group library, imported a 600 item .bib file, expecting it to show up in the group library and found it in my personal library -- and I already had most of those items, so now I have many duplicates (many of which were bad, and with which I had spent plenty of time curating). Very frustrating.

Any ideas how to revert that import would be appreciated, as well as thoughts on importing directly to group libraries. . .

(Off-topic, but I assume you mean that you deleted the items within that collection (via Ctrl/Cmd-Delete or right-click->"Delete Selected Items from Library") rather than just the collection itself, which would leave the contents in your library. If not, though, and in general, you can always sort your library by Date Added in the middle pane to delete items added at a particular time.)

so, I didn't see any follow up lately on this one. I am building a personal lib with 10000+ items in it, including attatched files. I am planning to buy some storage form Zotero, create a group library, and then post these items on the group lib. It looks like the recommended way to do this upload is to open my local library, select all the items (10000+), and carefully drag them into the newly created group library. Right? Perhaps do this in chunks, 100 or 1000 at a time, and see if it is working?

Just drag them into the group library. That's all. No import. No export.

The only limitation to this is that the collections can't be dragged-- just the items. So create the collections you need in the group, drag the items there.

I don't actually think Mendeley is doing much killing. They just have more full-time community people and look flashier and spend their time twittering and following google alerts. Zotero's one community person is focused more on the actual community, establishing connections with people who volunteer or contribute for Zotero, something that simply doesn't exist for Mendeley.

Check out the worlds 50 best Universities and look how many of them offer Zotero workshops and how many offer Mendeley workshops. The ratio is something like 5 to 1.

All that said, I really don't understand what you see as the problem with the group feature. dragging and dropping citations could hardly be easier?

well, sure there are many ways to improve them, but Daniel's frustration came from simply overlooking an existing feature and trying something way too complicated.
As for Mendeley, I just find those types of grandiose statements ("There is no future for Firefox", "Mendeley is killing" etc.) by people who've been using software for a day and dont' actually know much about it rather silly.

Apart from that, yes, collections should be draggable (and there's a ticket for that https://www.zotero.org/trac/ticket/1868 ) and as you know the web interface is being worked on quite a bit - with a lot of work going on in the background on cool features, e.g. server side translation, automatic tests of translators to make them more stable etc. As for your four interface proposals - the way I've been seeing Zotero devs work is usually doing large batches of work on one issue, so I'd expect them to get addressed when other issues of library--> group transactions get addressed. I know you've been frustrated by this at times (and in some cases, such as the notorious pdf parent item issue this has clearly dragged on for too long) , but you also have to see that for a small team of developers it's more effective to address one larger issue at a time than to jump from one small fixes to the next. Ideally, such small fixes could be submitted as patches from the community, but as of now I believe the only person outside of CHNM who understands the Zotero code well enough for that is fbennett.

Great! When can we expect that next major version?
