I'd like to share my experience with digitizing multiple-record sets. I have a set of five LPs that is being offered as a 3-CD (and MP3 file) set on Amazon (Elizabeth Soderstrom singing Rachmaninov songs). Fortunately, the Look Up Track Listing gave me all 86 track titles, which saved a lot, although I did have to manually determine the track boundaries. I recorded each of the 10 sides individually, to keep better track and to avoid recording all 5 LPs in one sitting on one side.
I used the Save Tracks tab to cleanup the audio (remove clicks and normalize) of the entire 10 sides.
I then appended [Disk 1] to the album title and proceeded to burn the first 26 songs on the first CD, and proceeded similarly for Disks 2 and 3. (I didn't want 5 CDs for 5 LPs).
I don't know if there is a better way to do this. I have found at least a couple of multiple record sets, or multiple individual related LPs, offered as a CD(s), with the track listing available on Look Up Track Listing. Of course, there is rarely a 1-1 correspondence between LPs and CDs.
