What kind of music is in the collection that your dad amassed?

I have a large collection of vinyl ablums (mostly rock).

I don't know how fussy you are about the cover art, however, this is what I do:

Very often the artwork for a CD is very close to the artwork for a LP of the same title.

Many LPs are in CD format and can be found on freedb. Load the data into OCD and edit as you see fit. Then go to the taskbar and do an internet search for "artist & album" I use Google.

When that comes up you can click on "show images" and if you're lucky, the cover may be there. If not, use the "search within results" at the bottom and type in the LP number. then it narrows it down and you may find your cover art somewhere in there.

Once you find the cover you want, right click on it and click copy. Then go to the album in your OCD, click the artwork tab and then paste.

There are loads of sites on the internet that have album artwork. I find a lot of them In something called "Rate Your Music" and another called "Musicstacks". I'm not 100% sure, but I think you can probably search through Racks and Tags and find album artwork to copy and paste. I haven't tried it.

Hope this was of some use to you.
