I was scraping around the web to find information on a particular release earlier today, and came across this:
hxxp://librarymusic.eklablog.com/
It's essentially just a fairly long list of library records and links to them on online storage sites - primarily upl***ed. I checked a few, and they seem to be good, albeit in mp3. But the selection is extensive, and might help some of you completists fill some gaps in your collections.
Hope this helps, and apologies if this is any sort of repost or prohibitted posting.
