An exclusive release might be a limited-distribution academic file or a special author-signed digital proof.

Ge Hong wrote cryptically. He deliberately misnamed ingredients to protect the "Heavenly Secrets." An exclusive translation includes footnotes explaining what "Dragon’s Subhumerus" (actually saltpeter) or "Three Yellow’s" (sulfur, realgar, and orpiment) refers to.
