The proposed book on Kärrbo parish in Västmanland, with the preliminary title "Kärrbo parish from the Middle Ages to the present", is based on source research and interviews with people in the parish. The manuscript comprises just over 30 chapters and is estimated to be about 200 pages long, including images. The latter has largely been collected in the parish's village archive and has been scanned for reproduction. The material for the book has been produced by a group of senior people with links to the parish. Among them, several have previously published books and scientific articles with a historical connection. Dr. Magdalena Hellquist has, among other things, written several books on proverbs and has been editor of editions of the diaries of the provost Muncktell from Västmanland in the early 1800s, including the one about Kärrbo. Professor emeritus Gunnar Grant at Karolinska Institutet, has published a book about the farm Frösåker in Kärrbo, published by Atlantis in 2008, as well as several articles in international journals in the field of "history of neuroscience". Elisabeth Westerdahl, a writer on antiquities, has published two books on the farm Kusta, located in the neighboring village of Irsta. Sture Källberg grew up in Kärrbo and began working as a freelance author and writer in the 1960s. He has 13 titles in his bibliography. Among these is "Rapport från medelsvensk stad - Västerås", which deals with his childhood in Kärrbo and the migration of people from the countryside to the city.
