Looking for information on stock warrants

Are there SEC filings specific to warrants? For example, BKS& aka BKS-WI, but I'm not seeing information about that in Barnes and Noble's 10-Q.

Is there some place to look up expiration and call price? Or is this pretty much limited to whatever is publicly available, for example, this GM page?
