I've given https://husserl.net/ a site I created 20 years ago to facilitate bibliometric studies of Husserl's corpus, a much-needed makeover. Go from keywords, to texts ordered by occurrence, to page references, to the text itself (courtesy of https://ophen.org/), in just a few clicks. Get a feel for when different ideas were prominent for Husserl. Lots of other custom features I'll post about later!
