Overview

Mission

The purpose of GeoBook Studio Inc. is: to present complex information using graphics as well as text to facilitate the efficient understanding of ideas.

What it reported doing in 2025

GeoBook Studio Inc. (GBS Inc.)'s primary program service is the production of print and digital books. Through this service, GBS Inc. seeks to improve understandings of the broad academic discipline of Big History and connected disciplines such as geology, anthropology, history, and science among students and the general population. In 2025, GBS Inc. sold 21 copies of its existing print books. Most of GBS Inc's efforts in 2025 focused on the development of its new book, "Big History of Martha's Vineyard," which will be the subject of increased promotional efforts and wider distribution. These efforts included extensive research, revisions, and direct work with experts in Martha's Vineyard's history. A preliminary digital version of "Big History of Martha's Vineyard" was released through Apple Books in August 2025 and sold its first copy. "Big History of Martha's Vineyard" is scheduled for release in print and expanded digital release in 2026.
