Got the books today. Still have to wait for the new scanner, as the one I have right now usually locks up after few pages which makes scanning 100+ page books difficult (new scanner ETA: end of this month, at the latest).
Anyway, some info about the contents of the books as promised.
Anime guidebook:
Artwork, character and episode guides, voice actor interviews and photos.
PSP Guide:
Lists and diagrams for different routes, character info, screenshots and some artwork.
Comic Anthology:
Full of non-H doujins. Few artworks and occasional 4koma. Mostly they're of Kirino or Kuroneko, but other characters are featured as well.
