This box of 600+ specimen cards holds a complete snapshot of the last metal type foundries in Germany. Produced 1958–1971, the Schriftenkartei (Typeface Index) represents the final effort to catalog all the country’s typefaces in production at the time. The cards are useful for researchers and designers as they share a common format and show complete glyph sets. Thanks to Michael Wörgötter, a set of these cards is now in our collection, and his high-res scans are online. https://letterformarchive.org/news/schriftenkartei-german-font-index/

This Schriftenkartei represents a fascinating example of a card index (#zettelkasten) as a database. This one obviously had a very narrow range of topics.

#typography + #zettelkasten = winning!
