Epic Tales of the Philippines is an anthology of epic stories, retold in narrative form, from original ballads and poems of major tribal groups of the country. Hitherto unpublished and published epics are expertly compiled and edited for individual reading and an invaluable source in the study of Philippine folkloristics and Asian literature.

The A to Z of the Philippines provides more than 400 hundred entries on important persons, places, events, and institutions, as well as salient economic, social and cultural aspects. The more than four centuries of the Philippines history covered by Guillermo, including the periods of Spanish and American dominance over the country, is neatly wrapped up in an introduction, clearly laid out in a chronology, complemented with statistical data in the appendix, and concluded with a bibliography allowing further research and study.
