We thought we'd share this - a "large-scale Anton Bruckner Internet portal that includes complete digital copies of all
manuscripts and first editions along with information on relevant
persons and places." For anyone needing to know more about Bruckner, it sounds like a great place to start!
Bibliolore is the acclaimed blog of RILM (Répertoire International de Littérature Musicale), which can genuinely call itself, "the World’s Most Comprehensive Music Bibliography".
The Whittaker Library at the Royal Conservatoire of Scotland is a subscriber to RILM (our students and staff can find RILM on our digital collections page), but anyone can visit Bibliolore's great blog.
