Most of the time you have to enter the info yourself, but I prefer it that way, actually.
However, some albums that you log into Catraxx via CDDB do contain discographical info, although, like I said, I prefer to do it myself.
CDDB comes handy because it gives you track titles and playing times.
CDDB is designed for cds, but there's also an additional program designed for Catraxx to import track listings of your lps. Pretty handy.
The potenital of Catraxx is almost infinite.
For instance,I know that musician I have on most albums in my collection is Paul Chambers. I have him on 72 albums.
Next is Lee Morgan. He's on 50 albums. Etc, etc.
Like I said, you'll have to spend time with it, and for some people it would mean years, depending on the size of the collections.
