The Library, also known as "Mary's Library," is a location in Harvest Moon: Back To Nature.
The library is run by Mary and is open to the public each day except for Mondays and holidays from 10am until 4pm. Here, you can read books, the majority of which were written by Mary's father, Basil. Many of the books are helpful to the player and talk about festivals, flowers, fish and mining. There are no recipes or cookbooks here.
The second floor of the Library connects to the second floor of Mary's Home. This is only accessible when you get close to Mary and her family. If the player plans on courting Mary, it is easy to find her in the library to give her gifts. If the player marries her, she will still work in the library but only on Sundays.
