Biology textbook, 2014 edition, compatible with the IB program. - Title: Biology - Authors: Andrew Allott, David Mindorff - Edition: 2014 - Publisher: Oxford University Press - IB Program Compatible: Yes - ISBN: 978-0-19-839211-8 This was used for IB studies. As there are many pages, I haven't been able to check them all, but I found one page with lines drawn on it. I did not find any other writing or markings to the best of my knowledge. I apologize if I missed anything. Due to the nature of the thin cover, there may be minor folds, scuffs, or color transfer, but the book itself is generally in good condition. I would be happy if someone looking for this book could make use of it.
