Motivation

The Wikidata:WikiProject 20th Century Press Archives aims at linking all folders of the collection to Wikidata. After the folders of the persons archives have been linked, next step is creating the metadata for the folders of the PM20 country/subject archives. (Currently, the external-id link redirects to a Skosmos page, from where the actual folder lists are linked under SEE ALSO shlist:... and walist:...). Jneubert (talk) 13:30, 13 July 2020 (UTC)
