Mercury Records made some of the finest and most natural sounding audio recordings ever made, mostly of excellent and committed performances of classical music. But this is not a history of Mercury records or even of the Living Presence series of recordings. My main focus was to create a list of all the Mercury Living Presence classical records. I am mostly interested in the stereo recordings, but there are also many earlier mono recordings of great interest, too, so I have included those also. Specifically, what is included is information on the SR 90000 series of stereo recordings and the MG 50000 series of mono recordings, but there is also a listing of the Wing classical reissue series. ***** Decades ago, when I began collecting Mercury records, and years later when I started collecting the CDs, I was looking for a complete list of all the Mercury Living Presence records and later the CDs. Though I found some information that was helpful, to get what I wanted, I had to make the list myself. I started with lists of records on the record sleeves of the albums, got some information from The Absolute Sound! magazine, and in the internet age, found useful information on several internet sites, but mostly to get the list I wanted, I had to dig up the information and build it myself. Having completed the list, it occurred to me that other collectors might find it helpful, too. So I put together a group of databases and spreadsheets in Microsoft Excel and Microsoft Works database format files and issued the databases I had created on a CD-rom disc in early 2013. By that time I had all the original series of CDs mastered by Wilma Cozart Fine, and many of the records that had been reissued on CD, and virtually all of the stereo records not issued on CD, plus most of the mono records in which I had a strong interest.
