The magazine Signum, in its first decades Credo, celebrates its 100th anniversary in 2020. The magazine provides information on church, culture and society from a Catholic Christian perspective. It constitutes a forum for reflection and exchange of ideas, where an international conversation on science, culture, social issues, philosophy and theology also takes place, and strives for accessibility without compromising a qualified level of appeal and stylistics. The anniversary anthology "Signum 100 years" contains a dozen thematically organized texts and reflects the journal's areas of interest. The writers are drawn from outside the journal's staff with the aim that their independent texts will give an idea of Signum's publishing in an appropriate social and cultural context and in a historical perspective. Topics covered include religious freedom, literary monitoring, dialog, integration/immigration, Catholicism and intellectuals.
