Keep public Library
Is it possible to give access to the public (or selected group) to use references in the Zotero library without giving access to edit or change anything?

1. You can just make your library -- or any group library -- public. That allows anyone on the web to see it online, (and drag references to their own library should they want to). No one else will be able to edit anything.
2. You can use a group with any settings, i.e. including a private group, and don't allow item editing for group members (only admins). That way, group members can e.g. use reference from that group library using word processor integration. This method would, for closed or private groups, also allow you to share attached files, which isn't possible via public groups.
And you can do 2. for any group by clicking on "Manage Library" here https://www.zotero.org/groups
Do I now have to drag my entire library into that group's library? Where should my colleague go to view my library?
This will place aliases for my items in his Zotero library, is that correct? Then he can use Zotero tools to search them, etc.?
You can't drag your entire folder structure -- you'd have to drag the (top level) collections one-by-one.
Are the items I share duplicated in my colleague's Zotero storage? Is there any additional burden on my storage?
Do the items I share with my colleague synch to stay updated in Zotero? What if I add new items to a collection?
