Where are these older Swedish musicalia?

According to the card-index at Statens Musiksamlingar (National Music library), 33 libraries have collections of music dating from before 1800: they are listed here.

Some have just a few items, most have about half-a-drawer-full of index-cards; of the 'big three', the Royal Academy of Music's collection takes 15 drawers of cards, Uppsala university library eight, and Lund university library three.

The collections are mostly in the older-established cultural centres in southern and central Sweden: only four are in Norrland.
