Urano, a young Japanese soon-to-be librarian, dies in an earthquake. She is reincarnated in another world as a young girl named Mayne, but learns books are scarce and only provided to prestigious elites.

Urano Motosu loves books and has an endless desire to read literature, no matter the subject. She almost fulfills her dream job of becoming a librarian before her life is ended in an accident. As she draws her last breath, she wishes to be able to read more books in her next life. As if fate was listening to her prayer, she wakes up reincarnated as Myne-a frail five-year-old girl living in a medieval era. What immediately comes to her mind is her passion. She tries to find something to read, only to become frustrated by the lack of books at her disposal. Without the printing press, books have to be written and copied by hand, making them very expensive; as such, only a few nobles can afford them-but this won't stop Myne. She will prove that her will to read is unbreakable, and if there are no books around, she will make them herself.—MAL Rewrite

This came right after the news that she would finally be able to work as a librarian like she had always dreamed of. When she regained consciousness, she was reborn as Main, the daughter of a poor soldier. She was in the town of Ehrenfest, which had a harsh class system. But as long as she had books, she didn't really need anything else. However, books were scarce and belonged only to the nobles. But that doesn't stop her, so she makes a decision... "If there aren't any books, I'll just create some."—Crunchyroll
