"The Complete World Heritage Encyclopedia: Official Textbook for the World Heritage Certification Exam, Level 1" - Complete Set (Volumes 1 & 2) World Heritage Certification Exam Office / NPO World Heritage Academy #WorldHeritageCertificationExamOffice #NPOWorldHeritageAcademy #Books #Geography/Geography&Maps #Certification #Qualifications #Travel #Overseas [About Volume 1] I've attached 5 index tabs to the top of the book. When I tried to remove them, the paper of the book seemed like it would peel off, so I'm selling it with the index tabs attached. I'm sorry! (´；ω；｀) There are no writings or markings, and no noticeable scratches or stains. The contents are like new. [About Volume 2] I haven't opened it since I bought it new. It will be sold as is."
