With Volume 15 of Aquatic Mammals, then Managing Editor Dr. Victor Manton created an index for the first 15 volumes of the journal. This index included authors and subjects for articles published in the journal. In keeping with Dr. Manton's approach, we have created two additional indices - one for Volumes 16 - 30 that is an author index and one for Volumes 31 - 40 that contains both an author and keyword indices. These files are available for free to interested readers. We will continue to add indices for Volumes 41, 42 and forward about every two years.
