I was really looking forward to this, having found EndNote so useful for keeping track of what I had read, and what I thought about articles when studying - so I approached Zotero with enthusiasm. First obstacle was "Download Zotero". I need to ask permission and get the IT Department to download anything. As my boss was away, the easiest way was to download it at home. That achieved - next I 'just' needed to discover how Zotero works. I've had a go capturing references from Newton, and to archive web-pages and pdfs, had a quick go at "dragging and dropping a citation, and created a quick bibliography.
Personally I can't see us using it in our library, although I can see its place in a departmental library. It will however be useful to have an understanding of it, to be able to answer student's queries, and as an alternative to EndNote for personal use. Setting up a group could also be useful for collaborative ventures.
Still must get on - more to explore....now I wonder what Mendeley is like?
