I realize you're just using this to get in a bit of Jeff-bashing but I'll explain anyway.

The new library set is likely a replacement for the "everybody gathers here" scenes that they used to just do in Derek's loft. They need an easily accessible space within the universe that doesn't require a lot of explanation to get everyone there.

With the refocusing of the plot onto the teens of Teen Wolf, a School Library (ala Buffy the Vampire Slayer) makes sense.

Speaking of Buffy, once they lost the Library in that show they created the "magic shop" as the replacement for that "gather" spot.
