The history of the family is one of the well-researched cross-sectional areas of social and mental history. However, this applies to the early modern period and the recent history from 1789 to 1914, not to that of the 20th century. Family contemporary history is a domain of family sociology, pedagogy, and psychology. It is presented as a resource to be developed in dialogue between historians and laypeople interested in family history. The theoretical part discusses the motivation for engaging with the family both within and outside of academia, as well as guiding perspectives and main lines of family development from the nuclear family to the patchwork family. The practical part addresses specific source issues in family historical project work.
