The 99% Invisible City
In October 2020, Kurt Kohlstedt and Roman Mars released The 99% Invisible City: A Field Guide to the Hidden World of Everyday Design. Published by Houghton Mifflin Harcourt, the book reached The New York Times Best Seller list in its first week of release.[40]
The book received critical acclaim for its ability to make complex civil engineering, city planning, and architectural concepts accessible. Kenneth T. Jackson, reviewing for The New York Times, described it as "altogether fresh and imaginative when it comes to thinking about urban spaces,"[41] while a starred Kirkus Review praised it as a "bible for the urban curious."[42] It was further featured on NPR's Science Friday and named a best book of the year by the Financial Times.[43]
Following English-language rollouts in the US, UK, Australia, and Canada, the book was translated into several languages, including Spanish, Czech, Chinese, Korean, and Japanese.[44] Mars and Kohlstedt were unable to travel for a physical book tour due to COVID 19, but were interviewed remotely by Hank Green, Seth Godin, Alexis Madrigal, and Kristen Meinzer as part of an alternative virtual book tour.[45] Mars also recorded the audiobook version.[46]
Beyond its commercial success, The 99% Invisible City has been adopted into the permanent collections of major academic libraries, including those at UC Berkeley and Yale University.[47][48] It is utilized as a foundational text in university curricula across multiple disciplines, including Urban Planning and Geography at San Jose State University and Architecture at the University of Toronto's Daniels Faculty of Architecture, Landscape, and Design.[49] In a professional context, the American Institute of Architects (AIA) has incorporated the book and its associated lectures into its Continuing Education Services (CES), allowing licensed architects to earn professional development credits through its study.[50]
