To accomplish its organizational purpose, Museums Alaska maintains a central office to receive and disburse information about museums, cultural centers and their activities, and to collect and share professional opportunities. Museums Alaska publishes the quarterly newsletter, Network, and organizes an annual meeting and conference to focus on the needs of Alaska museum professionals, volunteers, and their institutions.

More than 60 cultural institutions are represented in Museums Alaska with members as far north as Barrow and as far south as Ketchikan. The organization serves museums as remote as Anaktuvuk Pass Cultural Center, and as urban as the Anchorage Museum of History and Art. Membership is open to all individuals and institutions concerned about Alaska's cultural heritage.

Meetings of the general membership are held annually in an Alaska community. The annual conference provides a forum for discussion of museum issues, an opportunity to network and connect with peers, and a celebration to recognize outstanding professional contributions.

The Museums Alaska quarterly newsletter Network, connects this far-flung organization. Each Network contains information about Alaska's museums, including exhibit and program ideas, conservation techniques, administrative issues, advocacy, statewide news, and training opportunities. Network informs the public's understanding of the purposes and functions of Alaska's museums and cultural centers.
