In 2017 the Friends of Island History — a collaborative of organizations on and around Mount Desert Island, Maine — partnered with HistoryIT to survey local historical collections and determine how they could be made more accessible.

The thirteen organizations listed below contributed historical materials to be digitized in a shared catalog, allowing students, researchers, organization staff members and volunteers, as well as the general public to search across several collections simultaneously, and uncover valuable connections among the separate historical collections. A generous gift from the Charles Butt Foundation funded the initiative, called the History Trust. This website is the result of that initiative.
