The Swiss Army Knife for Journalists: Digital Investigative Tools in the era of Big Data is a book written by OjoPúblico co-founders David Hidalgo and Fabiola Torres. They describe the key tools that have been used in data journalism projects across the Spanish-speaking world and offer a deep-dive look at the growth in digital media sites in Peru where OjoPúblico is based. The book is available in Spanish and English.

Torres is now an ICFJ Knight Fellow spreading these practices to investigative teams in Colombia, Mexico and Central America.
