Tony, The albums that I've inherited cover all genres from classical to rock 'n' roll. There are even a few new age albums. The oldest album in the collection is from the mid 1950's and the newest is mid 1980's.

The suggestion to look for CD cover art is a good one and has worked for albums from the 70's and 80's. It's when I start looking for cover art for albums from the 60's and earlier that I run into a brick wall. The original publisher's don't even list the albums anymore. Not surprising.

For those older albums, here's what I've started doing. I scan the cover of the actual album. This takes two scans, one for the right and left sides. Since there is overlap with the two scans, I use Paint.net to merge the two scan images. I wind up with one huge file. I'm playing around with options to reduce the file size and get the image to a size I can use with OCD.

Many thanks for the sites you and Jazz_North suggested. I will definitely do some exploring on them.

Thanks again to all who've contributed.
