Which organization is the oldest and largest library association providing professional standards and guidelines?

• A. ALA
• B. Audio File
• C. Domain
• D. Big 6

Answer: (A)

The organization is the American Library Association. Founded in 1876, it is the oldest and largest library association, serving librarians and libraries by setting professional standards and providing guidelines for library services. It shapes practice through widely adopted documents such as the Library Bill of Rights, the Freedom to Read Statement, and the Code of Ethics, along with other standards and policy statements that guide libraries nationwide. The other options aren’t library associations—an Audio File isn’t an organization, Domain is a term, and Big 6 is a well-known information-literacy model used in libraries, not an association.
