Introduction: The National Library of Mongolia was established in 1921 based largely on the 8th Khalkha Jebtsundamba Library. In studying the tradition of collecting and preserving books in Mongolia, the subject can be divided into three categories:
1. Family collection
2. Palace/ Royal collections
3. Monastery collections.

This book, “The drug actions that are useful for any kind of ulcer, swelling, and injuries,” is a rare and valuable item of medical cultural heritage, existing in a single known copy. Therefore, this work was selected for incorporation into the research cycle.
