Plot
Motosu Urano, a book-loving college student who just got her Librarian certification and was supposed to enter the job of her dreams after graduation, was killed during a massive earthquake crushing her underneath a pile of her own massive collection of books.

Wishing for reincarnation in order to read even more, she got reincarnated to a world with a low literacy level and very few books, limited only to the nobility of the world. As she reincarnated as 5-year-old daughter of a lowly soldier, Maine, no matter how much she wants to read, there is no way there are any books around. If there are no books then what do you do? You make them yourself of course... What her goal is, to become a librarian no matter what, and to live a life surrounded by books. For starters she begins from making them.
