There didn't seem a good time to mention it before and, well, I've only just finished exploring it myself - Hogwarts Library is here in Lawrence. I wished for it at Christmas but I've been building in a few safeguards, to stop it from falling into the wrong hands, and, well, what with everything, it took me longer than expected.
I've cast a fidelius charm on it: for those of you who don't know what that is, it means no one will be able to plot or stumble across it unless they have been told where it is by the secret keeper, which is me.
If I die get sent home, everyone that I have told, in turn, becomes a secret keeper. That way, I hope it will continue to be useful, even if I am not here to oversee its use.
Before I tell anyone where it is, however, I'd like to give a warning: while many of the books it holds are standard books of spells, magical histories and directories, that doesn't mean the knowledge they hold can't be dangerous. And there are plenty of books which aren't standard at all and are just down right dark. I hope anyone I trust with the secret of its location will honour that trust and keep any information they gain there safe and confidential. Knowledge is power and I won't stand by and let the library be abused, if I can help it.
That being said, if you would like access, please feel free to contact me. The spell books may not be relevant to many of you here, but there are plenty of books which will be. I just hope it can make some kind of positive difference.
