* If the whole book in its Muggle-published form is supposed to be an artifact from the Potterverse, does that mean Dumbledore wrote the introduction years after his supposed death?
** Maybe this is another facet of his Will. He writes the commentary well before hand, then writes in his Will “in the event of my death, it is my request that these books should find their way to the muggle population”
*** Which of course leads to the question: how does Dumbledore - in his will or in person - have the right to publish an exact copy of Harry Potter's personal property?
*** Dumbledore, break the law? Surely not.
*** Maybe it was Harry's idea?
*** Dumbledore's intro specifically states Harry agreed to it.
** Is the commentary not simply in the original book? Seems quite logical that the textbook would include some of the history behind the classification of magical creatures. Dumbledore was a highly intelligent and decorated wizard. Not out of the realm of possibility that he leant commentary to a textbook. I think the book is meant to be the one that Harry actually used in class. Essentially Harry's copy has been duplicated and sold to muggles.
* Why do the graffities in the book reference the events up to the fourth book, but not afterwards? Harry and Ron gave up Care of Magical Creatures in their sixth year, but in their fifth they still should have used the book.
** It's possible that, that's when their copy was copied.
** Or they were a little more mature in their fifth year - [[FridgeBrilliance maybe one of Umbridge's Educational Decrees banned writing in books]].
*** [[TyrantTakesTheHelm Umbridge]] making a ''reasonable'' rule? Surely not.
*** Even a stopped clock is right twice a day. Dolores was a sociopath par excellence but on some level a lot of her comments were correct. Lying is wrong, after all.
** In RealLife this book was released between ''Goblet'' and ''Order'' (not to take away the validity of the above headscratchers, just pointing it out to anyone who doesn't know)
** They don't seem to study Dark creatures in their fifth year (or at least under Umbridge) or in 6th year either. So they probably stopped using it for class and therefore no longer had the opportunity to write in it.
** And it might be that this book only gives a general overlook of the creatures. When starting Care of Magical Creatures class, they're assigned a different book - so it's possible they just stopped using this one.
* Dude was kicked out of Hogwarts for "endangering human lives". Hogwarts. The school that has a house entirely dedicated to turning out what are for all intents and purposes wizard nazis literally since its founding. Just how dangerous was his research that even Hogwarts was like "Nah, we don't want none of that"?
