Copernicus Case Negatives

Why rely on books that guess about the topic's direction?
Our case negative handbook will offer negative on all of the cases we cut, as well as many more under the resolution. We hold off work on this book until after the major summer institutes, ensuring the most relevant evidence makes the cut.
Available in both Word and PDF formats.
As always, you can count on Big Sky for the freshest evidence. Our 100% no backfile guarantee means you won't be paying for the same cards over and over again.

An even better value as part of the Big Sky Plata package.

Available in electronic (Word and PDF) formats for only $30.
Our positions have the latest brinks, most current links, and impact cards that weren't culled from some backfile on the 1990 space topic. Each position is researched and developed fresh each year.
Not only are our positions ready to run when you receive them, they will help generate your own research.
