Books About Puerto Rico
For deeper reading: Jorge Duany’s academic work on Puerto Rican identity and diaspora, Esmeralda Santiago’s memoir When I Was Puerto Rican for a personal narrative of the island-to-mainland experience, and Moon Puerto Rico or Fodor’s Puerto Rico for traditional print guidebook depth on logistics this site doesn’t cover as a travel-format book would. For a unique look at the intersection of food and culture, dig into Illyanna Maisonet’s cookbook Diasporican: A Puerto Rican Cookbook.
This guide focuses on breadth and structure across many topics – for deep, single-topic dives (rum production history, colonial architecture, a specific municipality’s full historical record), these sources can help you go further.
