The major enhancements in this release are:

• Improved recognition and identification of person names. We now have annotated 80837 person names and identified 45479 of these. The Constantijn Huygens and the Descartes corpus are included in the cocitation analysis.
• First results of topic modeling are now available. For the Hugo de Groot, Constantijn Huygens, and Christiaan Huygens correspondences we include a calculated list of similar letters. By clicking on an item you can compare the letter texts.
