Can we get a list going of labels that offer HQ covers/booklets/notes on their sites? Additions/corrections are strongly desired. I don't know if this applies to their whole catalogues - I don't want to check every disc's page, but I view them offering this option for at least some releases to be a statement of intent, meaning that all future releases should be offered this way.
HQ covers & full booklets:Hyperion (the model for this concept - notes available in HTML or PDF booklets)
Chandos (the older issues aren't very good)
Toccata (very respectable website)
DaCapo (front covers, but the booklets are for paying downloaders only)
Sterling (in concept only: I find that their links either faulty or placeholders - presumably the latter)
Onyx (notes are also available in HTML)
ATMA ClassiqueHQ covers:Tudor (HQ front and rear covers)
Glossa (very limited implementation, and the notes are currently not full, just PR blurb)
Neos (HQ front cover)
Full notes:Soli Deo Gloria (it's in a PDF, but not booklet format)
Naxos/Marco Polo (also HQ rear covers for Naxos, but not front, for some reason)
LinnEmusic.com used to offer HQ front covers to non-paying users, but no longer do.
I view labels offering free artwork as a token of respect to people who buy their discs. I don't want to laboriously digitise the booklets - I want to download them in 10 seconds, and as such, tend to more closely support the labels which offer this functionality.
