The Atlantic Chapter of the Music Library Association (ATMLA) brings together members from Delaware, Maryland, New Jersey, Pennsylvania, Virginia, West Virginia, and the District of Columbia.. The Atlantic Chapter is open to anyone with an interest in music and libraries. We are librarians, support staff, performers, scholars, students and music lovers who use libraries. We hope you will consider joining our chapter. It’s a great way to network with others who do the kind of work you do and a great resource for sharing ideas.
