Below are some examples of the hundreds of textbooks I've worked on as an art buyer and/or photo researcher, mostly during my years at an educational publishing house that took on titles from every major textbook publisher in the U.S., and some geo-political supplemental materials by Rand McNally. In this work, I art directed illustrators, cartographers, graphic artists, and photographers on creative content, styles appropriate for specific grade levels, and accuracy (mathematical, historic, cultural, data, etc.).
