Sorry Syrlya, that's a question that puzzles Strange. Everyone should know that the books would be from the time of the Raven King. Shouldn't they? He gives Syrlya a bit of a confused look before he answers, "Of course they are. None of the theoretical magicians have published anything and Mister Norrell and I have only published articles."

He continues walking, but he's giving Syrlya a little frown, as dream logic tries to butt up against actual logic while Strange sorts this out.

"There's very few books of magic or books about magic that haven't been bought up already. I consider it a small miracle that Arabella and I were able to obtain the modest library that we have." It's got like ten books. Strange's personal library is much more modest than he's implying.
