I tried to see if I could find those books on Google to get the exact titles and author names, but after translating the first three it seems that they're just easter eggs linking to other Touhou characters.
Wouldn't be surprised to see a "Cucumber raising manual" by Kawakuro or something like that ...

Well, if I'm wrong and these books really exist (against all odds), please feel free to correct the translation!

She notified a librarian that 5 books were upside down? Couldn't flip them herself?
