The project In Care, in History includes a comprehensive literature review aimed at sourcing historical articles, reports and books on the histories of vulnerable groups.

To ensure that the process is systematic, Susanne Lindow of the Royal Danish Library will conduct literature searches and record and catalogue the material.

A proportion of the material cannot be found using databases and other search agents. These include the period's newspaper articles, which for the years 1945–1980 are not registered in a single database or printed bibliography. The project group will therefore work with museums, organisations and individuals who hold large collections of newspaper articles.
