My Uncle (RIP), a veterinary professor at UC Davis, CA would get a National Geographic or Smithsonian or other Nature/History/Culture book every birthday, Christmas or anniversary from his Mother. He seldom even opened them to read. You can see that I do not open the book fully to photograph the inside pages because most of the book has never been opened. If the pages, the cover, and the dustcover are perfect/zero damage I list it as "brand new" (never read). If the dust cover is slightly damaged, or if there is a name written inside the cover, I reduce to "like new". If there are other flaws I reduce to "very good". I think you can see pretty well from the pictures.
All shipping is flat rate (media mail).
The smaller books will be in bubble wrap inside a poly envelope. Larger books with be in boxes with bubble wrap.
Thank you!
