You can easily create a bibliography from the All Documents area, any collection or your search results list.
Navigate to the collection you want to use (or All Documents area or run a search and select items) and click the Create bibliography icon 
.
You can choose to create a bibliography for selected references or for all of the reference in the collection (or in All Documents if that's the view you are in).
Next, search for your output style and select it. Your formatted bibliography will be displayed in your browser for you to copy and paste into any word processing software.
