FactGrid is a wonderful, free and collaborative resource that the University of Erfurt in Germany has made available to the international historical community. Many potential users are unfortunately put off by its apparent complexity. It is true that an initiation is necessary to exploit all its possibilities. In the future, new tools should make it much easier to use. In the meantime, it is possible to use a certain number of tools that already exist on the platform.
Here I will introduce the FactGrid Viewer tool.
A first use of FactGrid is simply to search and browse the database. This is accessible to everyone, without the need to log in. However, the user interface (which is that of Wikidata) is not very engaging. In fact, it looks more like an input mask than a user interface.
