how to insert a whole mess of citations at once

We have a library that contains 1000 entries, which we want to output
into one Word file. 

When I select all of the citations and then try to insert them, EndNote
responds saying that I can only insert 50 citations at a time.

How can I get all of these citations into one word file (that is,
without having to do this in lots of 50).

Many thanks.
