The public library in Berkley, Massachusetts, has been serving the community since 1893, and Mia Maguire wants to make sure its doors are always open.

When the 9-year-old heard that the library could be closed due to budget cuts, she jumped into action, crafting a plan to raise money on Saturday by selling glasses of lemonade for 50 cents each. During her first hour selling outside the library, she made $100, and she ended the day with $625, including donations.
