The Historical Dictionary of the Philippines, Third Edition contains a chronology, an introductory essay, an extensive bibliography, and several hundred cross-referenced dictionary entries.

The voluminous book provides a range of international theories and methodologies in analytical folklore investigations, and a classification scheme based on genre is offered as the system of taxonomy for Philippine traditional materials. Lopez counts on the regional folklorists to refine the classification according to the texts of their respective areas. The different genres, too, are explained and examined in another part of Lopez's study. The reader will definitely find interesting and useful, the illustrative examples for each genre.

Part III features the people and Part IV the many facets of culture and society — language; ideas, beliefs, values; institutions; creative expression; and social and cultural change.
