This Island Directory provides an annotated list of nearly 2,000 of the significant islands of the world. Several criteria were used to determine how much detail is provided for the selected islands. The format has been designed to summarize many kinds of information to give an overview of the geographic ecological and human interest of islands. Where the data available are sufficient a variety of indicators are used to make listings and comparisons of islands easier. The size of each entry has been adjusted to the amount of data entered.
