Statistics

The following statistics are created by a SPARQL query on the Wikidata endpoint.

Folder statistics

Legend:

1. total folders = all published folders from the complete collection period of 1908 to 2005 (for subject headings and wares, no complete inventory of folders in the collection exists, so this number is very incomplete)
2. folders with docs = folders with digitized and publicly accessible documents (restricted due to intellectual property rights)
3. total linked to WD = total folders linked to Wikidata (via P4293)
4. w/docs linked to WD = folders with publicly accessible documents linked to Wikidata
5. percentage = quota of folders with documents linked to Wikidata

See here for lists of the individual linked PM20 folders
