Upvote, but not for the suggestion to lie.<p>It's a terribly inefficient system and all government grants should require any resulting publication be openly accessible. But until we get there, simply look for their website or send them a nice, short email with the publication in the subject line. If there are multiple authors, you could have more success with a middle author than the leading or trailing authors (first and last are often the lab head). An alternative is looking for an administrative contact on their website.
