The Reference Section in Helm Library has many print journal indexes & abstracts from allied fields that contain materials on philosophy and ethics. Some of the major ones are listed below with their call numbers.
Many other fields have materials that are related to philosophy. This is particularly true of sociology, which has historically had a great overlap. However, education, psychology, and other fields also have an overlap with philosophy. Art and music cover articles on aesthetics, and you can find biomedical ethics articles in the medical and nursing databases.
