Hello everyone. Just to report an improvement to the categorization system introduced today, which can be found at:
http://imslp.org/wiki/IMSLP:View_Genres
You'll now see new links to "[subgenres]" which will make navigating through the various types of work much simpler. For instance, if you click on the link next to "For 4 players", you'll now see all the available combinations of instruments involving four players. And you can marvel at the different types of opera, toy instruments, etc.
Around 91% of works on IMSLP have now been categorized, and our team are working hard to classify the remaining 2,830.
Happy New Year!
