Factual information benefits society as a whole when it's shared, so Fair Use protections are more robust when dealing with facts. Note that this only applies to the facts themselves, not to the presentation of the facts, which may include a separate creative element. Whether the facts were published or not is also relevant, because the court believes the original creator should have the first opportunity to publish. Your Fair Use protections will be weaker when dealing with unpublished works.
