The Library probably hasn't had a new book in at least 5 years, and the Library Publish section is now gone from DSiPaint (but not 3DSPaint, for some reason). Why not use the reader to read regular blogs? Like, an icon at the top would switch from regular view to book reader view, like how it's used in the Library, and at the same time do away with the Library section. They're based on blogs anyways.
