Island
An island or isle is any piece of sub-continental land that is surrounded by water. Very small islands such as emergent land features on atolls can be called islets, skerries, cays or keys. An island in a river or a lake island may be called an eyot or ait, and a small island off the coast may be called a holm. A grouping of geographically or geologically related islands is called an archipelago, such as the Philippines.
List of islands of Maine
The Code column refers to Maine Island Registry status. All islands coded as "R" are registered and privately owned. Those listed as "U" are unregistered and held in trust by the State of Maine (some of these may be privately owned but the owners did not register the islands). Islands listed as "E" are exempt from the registry requirements because they are either owned by the state or federal government or have four or more structures on them and were presumed to be privately owned. Islands listed as "T" are held in trust by the state and management transferred to a particular state agency or organization, such as the Maine Department of Inland Fisheries and Wildlife ("ME IF&W").
