The Hawai'i Pacific Journal Index serves as "an index to magazines and journals published in or about Hawaii and the Pacific." You can find the list of titles included in this index here.
The following are key journals on the Pacific islands to which UCLA users have access.
Here are other journals and magazines that cover the Pacific islands (some more peripherally). The UCLA Library has limited holdings for many of these titles. Some have ceased publication.
Here are some databases and indexes that should be useful in finding articles on this region. These resources are licensed so you may need to configure your computer to connect from off-campus.
