A main task of the state archive organization is to preserve and make available the public documents of state authorities, which by law are part of the national cultural heritage. The departments of the National Archives also have the opportunity to receive archives from the private sector (so-called individual archives), i.e. from companies, associations, private individuals, families, farms, foundations, etc. In order to increase the use and show the research potential, the archives of authorities are often highlighted, which is not as common in the case of the individual archives. The book "Ett västsvenskt kulturarv: de enskilda arkiven i Riksarkivet Landsarkivet i Göteborg" aims to provide an in-depth account of Landsarkivet's archive holdings from the private sector, mainly in Västra Götaland County. The reader gets a description of the individual archives from a number of different perspectives, an insight into how they have been handled and an understanding of the historical context of the archives. The book's ambition is also to shed light on the concept of archives by discussing some so-called archive landscape traces in time and space. In addition to general information about the National Archives' 2,200 individual archives, which comprise more than 22,000 shelf meters, a large number of entries in the archive documents are presented with examples of the content. The National Archives want to be a natural part of the research infrastructure, and with the help of the book the author highlights the research potential, both for private individuals, family and local history researchers and academic research.
