The site run by Discogs is a very valuable resource, listing many record issues, CDs, LPs and singles, frequently covering the different versions from various countries and reissues.
Recently there has been a lot of activity in adding details of Bing's LPs. It's a site worth looking at for details or just browsing. Over 1250 issues are listed, though not all are wholly correct. (For example one LP which I am sure would have been official is shown as unofficial).
