If you order regularly from Ace Records, you might well have the Ace Records Catalogue 2011. If not, you can download one for free.
Just go to the Ace Records website and you'll get all the soul, jazz, blues funk, beat, garage and more as a download. Or rather, a few downloads of PDF files, as the thing is so hefty!
Worth doing though, if only to spend the day looking at all the compilations you never got round to buying.
