written sources

Explanation:

Written sources are the basis for reconstructing events from the past and are referred to as archival material. They are divided into narratives, documents and publications. The documents are certainly the most significant source for historical research, since they were produced at the time they are talking about, mostly through the work of government bodies, institutions and significant individuals.

These are texts written on stone, clay tiles, papyrus, parchment, paper or other material; today, written sources are mostly kept in archives and libraries.
