This is a fairly academic book about classification as infrastructure and it looks at a few specific instances (international death classification, tuberculosis classification, new nursing tasks trackers) and the way they both show and shape culture. It’s heady and interesting at the same time as it’s uneven and a little slow going. Most of the chapters were great but one in particular seemed out of place. The writers of the book have big vocabularies which was great but sometimes off-putting. This book gave me some new ways to think about edge cases in classification systems and the social assumptions that surround them.
