Contact your state and federal Congress members to advocate for funding and share what your library means to you. Support ALA's efforts to protect open access and digital infrastructure. You can also directly support your local library through donations or by joining your library's Friends group.

“We believe that memories and treasures should last a lifetime and beyond, and that these physical and digital materials support both community and cultural identities. Focusing on preservation for a designated week every year raises awareness of the role libraries and other cultural institutions play in preservation, by sharing information to help make informed decisions that help your collections last for the future.”
