The Library depends on a unique financial partnership between government agencies and private donors to meet the costs of providing open access to our great center of culture and learning - free of charge to all.

Thanks to the generous commitment of dedicated friends, the Library can continue to provide books and information, as well as research, and educational programs to the 30 million users who come though our doors or visit us online each year.

By supporting the Library, you can become a part of this important mission. There are many different ways you can help.
