I've got two turntables and a few thousand albums, and have only tried digitizing a few things thus far.
Several years ago I digitized my high school choral department albums, mainly for a classmate who hadn't heard them in 50 years, but I hadn't either and I was very glad I'd done it. There were around eight albums and it was quite the project, getting them recorded, separating the tracks, and documenting it all as accurately as possible.
I then thought to try preserving some live performance recordings Levine had provided for a few of us on vinyl during the school years, and I started with our one-shot Mahler 6th. That went pretty well, too, but was a lot of work in the editing department because I was determined to get rid of or minimize some clicks and pops in a few passages.
I think the only other thing was that Jerome Robbins album I did quickly, (and with hum in the system!) so BK could check out the stereo release.
My method: I ran audio cables from the phono pre-amp into a Zoom H5 recorder, and monitored the recording with headphones running out of the Zoom. (This is a wonderful device that I should be using for many things, and I so rarely think of it.) I captured the audio as WAV files for best results, then popped the memory card into the laptop and used the free program Audacity to clean up the beginnings and ends, splice together where necessary, and remove noises. I save the audio as WAV or MP3 or both, as appropriate.
