Reading about the culture, folklore, and mythology of the Philippines was difficult for a long time. While some people are able to rely on the stories told by their parents, lolos, and lolas, others (like myself) needed to rely on online sources like The Aswang Project and PHSpirits for a long time.
Over time, it's been easier and easier to find books that provide some insights into our mythos. Here's our ever-growing book list of what we have been using to create our artwork and plushies:
