The Institution Trilogy is a collection of projects made by Anders Petersen during the 1980's and 1990's. This volume combines three institutional spaces; Prison, Elderly Care and Mental Institution. Each was published as independent books; Fängelse (1984), Rågång till Kärleken (1991), Ingen har sett allt (1995). The Institution Trilogy brings together all three projects with fresh editing, sequencing, texts and framed in a conceptual design. The book serves as a historical document of life in these Swedish institutions and illustrates the evolution of Anders Petersen's documentary photography moving towards a greater subjective sensibility. New texts from Niclas Östlind, Michael Grieve and an interview with Anders Petersen.

Anders Petersen (born 1944) is a Swedish photographer, based in Stockholm. He makes intimate and personal documentary-style black and white photographs. Petersen studied photography under Christer Strömholm in Sweden from 1966 to 1967. For three years beginning in 1967 he photographed the late-night regulars in Café Lehmitz, a bar in Hamburg, Germany. The resulting photobook was first published in 1978 by Schirmer/Mosel in Germany. Café Lehmitz has since become regarded as a seminal book in the history of European photography. Petersen has published more than 20 books. He has had exhibitions at Bibliothèque nationale de France, Liljevalchs konsthall, MARTa Herford, and Museum of Contemporary Art of Rome. His work is held in the collections of the Museum of Modern Art in New York and Moderna Museet in Stockholm.
