New edition of the directory: comparison tables on the city pages, a summary sentence with the directory's own figures on every country, city and style page, the directory in numbers with open data (JSON and CSV, CC BY 4.0), a glossary, a methodology page with the responsible person and a disclosure, a seal with the month of the last check on every entry, this changelog. City pages now exist from two studios; the addresses of places with a single studio redirect to the country page. Pages load without JavaScript.
Directory started with 14 studios in Germany, Austria and Switzerland, recorded from the studios' own websites; research rounds in the same days bring Germany, Austria, Switzerland, the Netherlands, France, the United Kingdom, the United States, Canada and Australia to 250 studios in 182 places.
