For poor college students looking for another way to save money and have fun in Boston for free, the library probably isn't the first place they'd think to go. It should be.

A program sponsored by the Boston Public Library allows library card holders to reserve donated passes to museums and other attractions around Boston. They can use them for one day before returning them to the library for someone else to use—sounds like borrowing a book, right? The passes can be reserved ahead of time, and must be picked up from the library either the day of or the day before their use. Any student in the Boston area can get a library card, including Harvard students!

Many of these passes cover admission for multiple people, giving an awesome excuse to break out of the Harvard bubble with friends. Institutions participating in the free or discounted admission program include: the New England Aquarium, the New England Zoo, the Institute of Contemporary Art, the Museum of Science, the Museum of Fine Arts, the Children's Museum, and many more locations around Boston.

Go nuts. The seals are beckoning.
